Electrical Symbols

Electrical symbols or electronic circuits are virtually represented by circuit diagrams. There are some standard symbols to represent the components in a circuits. This article gives some of the frequently used symbols for drawing the circuits.

There are many electrical and electronic schematic symbols are used to signify basic electronic or electrical device. These are mostly we used for draw circuit diagrams. Below are different kind of symbols we mentioned category wise.

Hope this information will helps to understand clearly. It is informative, most of the symbols are already known. However, few of them added up my information. Few alike information may be shared. Sooper knowledge for basic learners of electronics technician as wel as technologist! Electronics is my passion. What devices are inputs outputs and controlled deviceses. Its really hard not knowing what they act as because I only know a wire a resistor a bulb and a switch and battery? It has only 2 leads and it very similar in shape to a trimpot, except no dial-like structure.

If anyone has any idea what this component does, let me know! It came in an arduino kit that did seem to mention the component… So maybe it was a mistake. M component tester reads as unknown or broken component. I love your article as it shows a lot of symbols in the world of electricals. It helps a lot of people in the field of electrical since they might learn new symbols or recall the things they have forgotten.

Anyways, this is a great post! I see a symbol in a circuit that looks like 2 filled in triangles that look like arrows pointing at each other but the points are not touching. There is no nomenclature by this symbol and it is used frequently in the circuit drawing. Does anyone know what this is? Everything is ok exept for the bulb. But thanks, you helped me out with my homework.

Your email address will not be published. Comments Really nice informations are here. M an engineering student. And it help mee for my electronic subject. Lovely… How do I get direct and correct circuit diagram from here. I love the information contained herein.

I say kudos and more grease to your elbow. I so much love dis page,10ks very much,God will increase ur knowledge. Leave a Reply Cancel reply Your email address will not be published. Change Ad Consent. Wires Represents a conductor that conducts electrical current. Also called a power line or electric line or wire.

Connected Wires Represents the connection of two conductors. Dot shows the junction point. Input Bus Line Represents a bus for input or incoming data. Output Bus Line Represents a bus for output or outgoing data. Terminal Represents start or end point. Bus Line Represents a number of conductors joined together to form a bus wire. This goes to OFF state when it is released. Poles define the number of circuits it can be connected to and throws defines the number of positions that a pole connects.

This switch allows the current to flow in any one of the two directions by adjusting its position. This switch can drive two circuits at a time. This can connect the four circuits by changing the position.

Relay Switch This represents the relay switch. It applies DC supply to the circuit. Constant Current Source The symbol represents an independent current source which delivers constant current. Controlled current Source It is a dependent current source. Usually depends on other sources voltage or current. Controlled Voltage Source It is a dependent voltage source. Single Cell Battery This provides supply to the circuit. Multi Cell Battery Combination of multiple single cell batteries or a single large cell battery.

The voltage is usually higher. Sinusoidal Generator Represents sine wave generator. Pulse Generator Represents pulse or square wave generator. Triangular Wave Represents triangular wave generator.

Ground It is equivalent to theoretical 0V and is used as zero potential reference. It is the potential of perfectly conducting earth. Signal Ground It is a reference point from which the signal is measured.

There may be several signal grounds in a circuit due to the voltage drops in a circuit. Chassis Ground It acts as a barrier between user and the circuit and prevents electric shock.

Fixed Resistor It is a device that opposes the flow of current in a circuit. These two symbols are used to represent fixed resistor. Rheostat It is a two terminal variable resistor. They are generally used to control the current in the circuit. Generally used in tuning circuits and power control applications like heaters, ovens etc. Preset It is a mini variable resistor. It is also called Trimmer Resistor or Trim Pot. The resistance is adjusted with rotary control present on top of it with the help of a screw driver.

They are used to adjust the sensitivity of the circuit like temperature or light. Thermistor It is a temperature sensitive resistor. They are used in temperature sensing, current limiting circuits, over-current protection circuits etc. Varistor It is a Voltage Dependent Resistor. It has non-linear current-voltage characteristics. Generally used in circuit protection from voltage surges and excessive transient voltages. The resistance of magneto resistor varies according to the external magnetic field strength.

They are used in electronic compass, ferrous material detection, position sensors etc. The resistance of LDR varies with the intensity of the light incident on it.

They are generally used in light sensing applications. Tapped resistor A wire-wound type fixed resistor with one or more terminals along its length. Generally used in voltage divider applications. Attenuator It is a device used to lower the power of a signal.

They are made from simple voltage dividers and hence can be classified in the family of the resistors. Memristor The resistance of memristor is varied according to the direction of flow of charge.

Non Polarized Capacitor Capacitor stores the charge in the form of electrical energy. These two symbols are used for non-polarized capacitor. Non-polarized capacitors are big in size with small capacitance.

They can be used in both AC and DC circuits. Polarized Capacitor Polarized capacitors are small in size but have high capacitance. They are used in DC circuits.

They can be used as filters, for bypassing or passing low frequency signals. Electrolytic Capacitor Almost all electrolytic capacitors are polarized and hence used in DC circuits. Feed through Capacitor They provide low impedance path to ground for high frequency signals.

Variable Capacitor The capacitance of the variable capacitor can be adjusted by turning the knob.

Today, circuit symbols and their usage has been pretty much standardised. This enables anyone to read a circuit diagram and know what it does relatively quickly. Schematic symbols are used to represent different electronic components and devices in circuit diagrams from wires to batteries and passive components to semiconductors, logic circuits and highly complicated integrated circuits. By using a common set of circuit symbols in schematics, it is possible for electronic engineers around the globe to communicate circuit information concisely and without ambiguity. It does not take too long to learn what the different circuit symbols mean.


A resistor impedes the flow of electricity through a circuit. Resistors have a set value. Since voltage, current and resistance are related through Ohm's.


Electrical & Electronic Symbols

Electronic component symbols are used to denote the components in circuit diagrams. There are standard symbols for each of the components which represent that particular component. Here in this article, we are explaining some basic and mostly used electronic components with their symbols. Symbol of the resistor is represented by Zig-Zag lines between two terminals. It is a common and widely used symbol in schematics.

An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products , available in a singular form and are not to be confused with electrical elements , which are conceptual abstractions representing idealized electronic components. Electronic components have a number of electrical terminals or leads.

Learning about basic electronics and creating your own projects is a lot easier than you may think. You will then learn about schematic diagrams and how they are used to design and build circuits. And finally, you will put this information to use by creating your first basic circuit.
