Electrical symbols or electronic circuits are virtually represented by circuit diagrams. There are some standard symbols to represent the components in circuits. This video gives some of the frequently used symbols for drawing circuits. There are many electrical and electronic schematic symbols used to signify basic electronic or electrical devices. These are mostly used for drawing circuit diagrams. Below are the different kinds of symbols we mentioned category-wise. Hope this information will help to understand clearly. – Wires, Switches, Sources, Ground, Resistor, Variable Resistor, Capacitor, Inductors, Diodes, Transistor, Logic Gates, Amplifiers, Antenna, Transformer, Miscellaneous.
