A block diagram is a specialized, high-level flowchart used in engineering. It is used to design new systems or to describe and improve existing ones. Its structure provides a high-level overview of major system components, key process participants, and important working relationships. A block diagram provides a quick, high-level view of a system to rapidly identify points of interest or trouble spots. Because of its high-level perspective, new turkish series 2020 may not offer the level of detail required for more comprehensive planning or implementation.

A block diagram will not show every wire and switch in detail, that's the job of a circuit diagram. A block diagram is especially focused on the input and output of a system. It cares less about what happens getting from input to output. This principle is referred to as black box in engineering.

Either the parts that get us from input to output are not known or they are not important. Block diagrams are made similar to flowcharts. You will want to create blocks, often represented by rectangular shapes, that represent important points of interest in the system from input to output.

Lines connecting the blocks will show the relationship between these components. In SmartDraw, you'll want to start with a block diagram template that already has the relevant library of block diagram shapes docked. Adding, moving, and deleting shapes is easy in just a few key strokes or drag-and-drop.

SmartDraw's block diagram tool will help build your diagram automatically. Block diagrams use very basic geometric shapes: boxes and circles.

The principal parts and functions are represented by blocks connected by straight and segmented lines illustrating relationships. When block diagrams are used in electrical engineering, the arrows connecting components represent the direction of signal flow through the system. A block diagram can also be drawn in increasing detail if analysis requires it.Electrical circuit is an interconnection of electrical components.

An electrical circuit consists of batteries, resistors, inductors, capacitors, switches or transistors. An electrical network consists of a closed loop. A circuit is a closed path where electrons flow in a wire. As long as the copper wire is allowed to itself, the electrons drift between the atoms but never leave the copper.

However, when we connect this copper wire to a battery the free electrons will be driven towards the positive terminal of the battery. This pushing force is called Electromotive force E. The E.

And usually, it is called voltage. As a result of this voltage, an electron motion takes place. This motion is known as electron current or electric current. We can measure current by connecting an ammeter between copper wire and voltage source.

A complete circuit is a never-ending loop of electrons. If we take a wire and loop it around, it forms a continuous path in which electrons can flow forever. This is a primary concept of a circuit.

A circuit diagram is a visual display of an electrical circuit.

There are mainly two types of circuit diagrams:. Suppose we want to draw a simple circuit in which battery is connected to LED in such a way that positive terminal of the battery is connected to positive terminal of LED and negative terminal of the battery is connected to negative terminal of LED.

Then it can be represented as:. If in a simple circuit one terminal is disconnected, then there is no flow of current through that circuit. This is said to be an open circuit or no load condition. An electric circuit has a source of Electromotive force and a load. This load acts as a conductor path. If the current flows through the load it is considered as a closed circuit.

If in a simple circuit, current can flow from one terminal of the battery to another without any discontinuation is said to be closed circuit. If the positive terminal of the battery is directly connected to the negative terminal without any resistance between them is said to be a short circuit. Other than the above circuits, components in an electric circuit can be arranged in two different ways and that are in series connection and in parallel connection.

If in a circuit, components are connected in series then the circuit is known as a series circuit. In a series circuit, current through each component is same and voltage supplied is the sum of the voltage across each component. If a wire joins the battery to one lamp, to the next lamp and then back to the battery, the lamps are said to be connected in series.

If in a circuit, components are connected in parallel then the circuit is known as parallel circuit. In a parallel circuit, the voltage across each component will be same and total current applied is the sum of current through each component. If a lamp is connected to the battery and another lamp is connected in a separate loop with first lamp, then lamp is connected in parallel connection.Products Solutions Samples Buy.

Use these signs to annotate or specify characteristics of objects in electrical drawings, electronic schematics, circuit diagrams, electromechanical drawings, and wiring diagrams, cabling layout diagrams.

Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job". A complete set of working drawings for the average electrical system in large projects usually consists of: 1 A plot plan showing the building's location and outside electrical wiring. Electrical drafters prepare wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wiring in communication centers, power plants, electrical distribution systems, and buildings.

Qualifying symbols. Electrical Engineering. The vector stencils library "Delay elements" contains 12 symbols of delay elements for drawing electrical schematics and electronic circuit diagrams.

It operates on analog signals whose amplitude varies continuously. An example is a bucket-brigade device. Other types of delay line include acoustic, magnetostrictive, and surface acoustic wave devices.

A series of RC networks can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed of impulses in the medium. Delay element symbols. The vector stencils library "Transmission paths" contains 43 symbols of power transmission paths, electronic circuits, bus connectors and elbows, terminals, junctions, and concentrators.

Use it to annotate electrical diagrams, electronic schematics and circuit diagrams. Many transmission media are used as communications channel. For telecommunications purposes in the United States, Federal Standard C, transmission media are classified as one of the following: 1 Guided or bounded - waves are guided along a solid medium such as a transmission line.

One of the most common physical medias used in networking is copper wire. Copper wire to carry signals to long distances using relatively low amounts of power. The unshielded twisted pair UTP is eight strands of copper wire, organized into four pairs. Another example of a physical medium is optical fiber, which has emerged as the most commonly used transmission medium for long-distance communications.

Optical fiber is a thin strand of glass that guides light along its length. Multimode and single mode are two types of commonly used optical fiber. Multimode fiber uses LEDs as the light source and can carry signals over shorter distances, about 2 kilometers. Single mode can carry signals over distances of tens of miles. Wireless media may carry surface waves or skywaves, either longitudinally or transversely, and are so classified.Circuit diagrams are maps used to design and build electronic devices.

This article describes connections, components, history, and tools used to create circuit diagrams. Unlike terrain maps which might have mountains, streams, buildings, trees, and other pieces, circuit diagrams only have two pieces:. An engineering degree is not required. Circuit diagrams also are widely available for many different projects.

Components also can be found easily. This article provides a high level overview of circuit diagrams and how they work. The Learn More section below provides links to more detailed descriptions and resources. Also note there is a difference between circuit diagrams, which describe a detailed electronic system, and a schematic diagram which may describe the same system but also include concepts and other abstract details. This article describes circuit diagrams used to build electronic projects.

Circuit diagrams map the flow of electricity through a system. The flow must complete a circuit, for example, from the positive node on a battery to a resistor to a lamp and back to the negative node of the battery.

This is the simplest form of a circuit diagram. From this simple circuit, you add other elements, in this case, a single pole single throw SPST switch to turn the circuit on or off which turns the lamp on or off:. The lines that connect each part of this diagram, from the positive pole of the battery on the left to the light on the right and back to the negative pole of the battery, could be wires or copper laid out on a circuit board.

More interesting is the fact connecting the positive and negative poles of a battery to create a circuit causes a collision of positive and negative electrons in the lamp bulb which, in turn, causes the light filaments to glow. While the circuit diagram shows conventional circuit flow, from positive to negative poles from the power source, the reality of how electrons flow is slightly different.

There is more complexity in these simple diagrams. My diagrams above are only to illustrate the idea of a circuit. From this elementary circuit diagram, you can diagram then build a wide range of electronics projects, from simple light switches and bulbs to sound systems to computers.

There are many different components that show up in circuit diagrams. A complete diagram includes a data sheet to describe all connections and components which can be used as a parts list to buy components. Here are some common types of components you might see in a circuit diagram.

The history of electronic components goes back at least to the invention of capacitors by Leyden in However, simple batteries may have been in existence for at least two thousand years, for example, the Baghdad Battery which appears to use copper, iron, and bitumen to generate electron flows. While some say the battery is evidence of ancient aliens, if it is a battery, more likely it was used to electroplate gold on to silver objects.

I first came across a mention of this battery while reading the memoirs of Ibn Battuta, a Berber from North Africa who traveled from Morocco to China and back from to His book describes a lot of interesting technology. In more modern times, circuit diagrams helped early developers of computer systems to build electronic systems to specifications, as well as reference earlier designs to improve them.

Today circuit diagrams are used mostly to create electronic systems, either by individuals or through mass production.

What is an Electrical Circuit?

The history of circuit diagrams involves people finding common ways to describe electronic components. Infor example, the International Electrotechnical Commission IEC started work to develop a common set of terms and symbols to describe electronics.

Symbols were created for measurements and graphic representations of electronic objects.Optocoupler is a component which uses light energy to connect two different electrical circuits or transfer energy from one circuit to another circuit.

Two circuits are completely electrically isolated to each other that means there is no electrical connection between them. Optocoupler has also some different names such as Opto-isolator, optical isolator, photocoupler, etc. Optocoupler mainly comes within ICs. Let's see what inside an optocoupler IC. As you see in the above figure the Optocoupler IC divided into two sections, one is the Light emitter section and another section is a light receiver or light sensor.

Another element is a light receiver such as it may be a Phototransistor. We know that when a light is applied to the base of the phototransistor it conducts current.

This principle is used in the optocoupler. So when we give electricity to the optocoupler then it creates a light which may be visible or Infrared and it is false upon the base of the transistor hence the transistor starts conducting current. When the applied light is off then the transistor stops conducting.

“Ladder” Diagrams

In Six terminals optocoupler, the 6th no pin is connected to the base of the transistor to control the sensitivity. In Photo-Darlington, two transistors are used. When IR light falls upon the base of one transistor it turns on the other transistor. The main application of optocoupler is to isolate two different electrical circuits. Optocouplers are used for ground isolation purposes. Optocouplers are used for high voltage monitoring and sensing circuits.

Optocouplers are used in lamp dimmer circuits. Optocouplers are also used in Motor control circuits. Optocouplers are used in lighting control circuits.

Optocouplers are used in switch mode power supply SMPS. Optocouplers are used in DC to DC converter circuits in automobiles. You can see in the above circuit diagram, the pin 1 and 2 of the optocoupler are connected to a DC source through a switch and a resistor. Read Also:. Thank You For Visiting the Website.

The vector stencils library "Transformers and windings" contains 29 element symbols of transformers, windings, couplers, metering devices, transductors, magnetic cores, chokes, and a variometer. Use it to design the electromechanical device schematics and electronic circuit diagrams.

Transformers may be used in step-up or step-down voltage conversion, which 'transforms' an AC voltage from one voltage level on the input of the device to another level at the output terminals. This special function of transformers can provide control of specified requirements of current level as an alternating current source, or it may be used for impedance matching between mismatched electrical circuits to effect maximum power transfer between the circuits. A transformer most commonly consists of two windings of wire that are wound around a common core to induce tight electromagnetic coupling between the windings.

The core material is often a laminated iron core. The coil that receives the electrical input energy is referred to as the primary winding, while the output coil is called the secondary winding. An alternating electric current flowing through the primary winding coil of a transformer generates an electromagnetic field in its surroundings and a varying magnetic flux in the core of the transformer.

By electromagnetic induction this magnetic flux generates a varying electromotive force in the secondary winding, resulting in a voltage across the output terminals. If a load impedance is connected across the secondary winding, a current flows through the secondary winding drawing power from the primary winding and its power source.

Wikipedia] "An electromagnetic coil or simply a "coil" is formed when a conductor is wound around a core or form to create an inductor or electromagnet. When electricity is passed through a coil, it generates a magnetic field. One loop of wire is usually referred to as a turn or a winding, and a coil consists of one or more turns.

For use in an electronic circuit, electrical connection terminals called taps are often connected to a coil. Coils are often coated with varnish or wrapped with insulating tape to provide additional insulation and secure them in place. A completed coil assembly with one or more set of coils and taps is often called the windings. Windings are used in transformers, electric motors, inductors, solenoids, loudspeakers, and many other applications. Transformer and winding symbols. Electrical Engineering.

The simplest vacuum tube, the diode, contains only two elements; current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode. Addition of a third and additional electrodes allows the current flowing between cathode and anode to be controlled in various ways. The device can be used as an electronic amplifier, a rectifier, an electronically controlled switch, an oscillator, and for other purposes.

Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. Some electron tube devices rely on the properties of a discharge through an ionized gas. Wikipedia] "The EL34 is a thermionic valve or vacuum tube of the power pentode type. It has an international octal base indicated by the '3' in the part number and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters.

Wikipedia] This circuit diagram sample was redrawn from the Wikipedia Commons file: EL34 schematics circuit diagram.Ladder diagrams are specialized schematics commonly used to document industrial control logic systems.

If we wanted to draw a simple ladder diagram showing a lamp that is controlled by a hand switch, it would look like this:.

These designations have nothing to do with inductorsjust to make things confusing. The actual transformer or generator supplying power to this circuit is omitted for simplicity. In reality, the circuit looks something like this:. Typically in industrial relay logic circuits, but not always, the operating voltage for the switch contacts and relay coils will be volts AC.

In the real world, that wire would be labeled with that number, using heat-shrink or adhesive tags, wherever it was convenient to identify. These wire numbers make assembly and maintenance very easy. Each conductor has its own unique wire number for the control system that its used in. Wire numbers do not change at any junction or node, even if wire size, color, or length changes going into or out of a connection point.

Of course, it is preferable to maintain consistent wire colors, but this is not always practical. What matters is that any one, electrically continuous point in a control circuit possesses the same wire number. Take this circuit section, for example, with wire 25 as a single, electrically continuous point threading to many different devices:.

In ladder diagrams, the load device lamp, relay coil, solenoid coil, etc. Here, the lamp load is located on the right-hand side of the rung, and so is the ground connection for the power source. Suppose that wire 1 were to accidentally come in contact with ground, the insulation of that wire having been rubbed off so that the bare conductor came in contact with grounded, metal conduit.

This time the accidental grounding of wire 1 will force power to the lamp while the switch will have no effect. It is much safer to have a system that blows a fuse in the event of a ground fault than to have a system that uncontrollably energizes lamps, relays, or solenoids in the event of the same fault. For this reason, the load s must always be located nearest the grounded power conductor in the ladder diagram. In Partnership with Vicor.
