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 electrical symbols free download. 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.
a little confused about the chassis ground and signal ground symbols, are they correct? because google says otherwise. 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? thanks you so much sir for share information, i am long time search electronic information, thanks a lot. Everything is ok exept for the bulb.
the build is a circle with a X inside it. But thanks, electrical symbols free download, you helped me out with my homework. Your email address will not be published. Tutorials Symbols Courses Calculator Contact Menu. Generalelectrical symbols free download, Most Popular. March 19, By Administrator.
Also called a power line or electric line or wire. Connected Wires Represents the connection of two conductors, electrical symbols free download. 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. SWITCHES Push Button Normally Open This switch is in ON state when the button is pressed otherwise it is in OFF state. Push Button Normally Closed This switch is initially in ON state. This goes to OFF state when it is released. SPST Switch Single pole single throw is abbreviated as SPST.
Poles define the number of circuits it can be connected to and throws defines the number of positions that a pole connects. SPDT Switch Single pole double throw is abbreviated as SPDT.
This switch allows the current to electrical symbols free download in any one of the two directions by adjusting its position. DPST Switch Double pole single throw is abbreviated as DPST. Electrical symbols free download switch can drive two circuits at a time. DPDT Switch Double pole double throw is the full form of DPDT, electrical symbols free download.
This can connect the four circuits by changing the position. Relay Switch This represents the relay switch. This can control the AC Loads using the DC voltage applied to the coil, electrical symbols free download. SOURCES AC Supply This represents AC supply in the circuit.
DC Supply This represents the DC power supply. It applies DC supply electrical symbols free download 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. Wave Generators Sinusoidal Generator Represents sine wave generator. Pulse Generator Represents pulse or square wave generator. Triangular Wave Represents triangular wave generator.
GROUND SYMBOLS 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. RESISTOR SYMBOLS Fixed Resistor It is a device that opposes the flow of current in a circuit. These two symbols are used to represent fixed resistor. VARIABLE 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, electrical symbols free download. They are used to adjust the sensitivity of the circuit like temperature or light. Thermistor It is a temperature sensitive electrical symbols free download. 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. Magneto Resistor They are also called as Magnetic Dependent Resistors MDR. 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. LDR They are also called as Photo Resistors. 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 electrical symbols free download 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. CAPACITOR Electrical symbols free download Non Polarized Electrical symbols free download 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.
