Description of Electrical symbols

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.
