To do:

We have to draw the symbols for following components of electrical circuits:

Connecting wires, switch in the ‘OFF’ position, bulb, cell, switch in the ‘ON’ position, and battery.

Solution:

Before drawing symbols of the components used in circuit, let us discuss a little about the importance of the symbols used in an electric circuit:

Importance of symbols in an electric circuit diagram: 

To represent an electrical circuit in diagrams different symbols are used for different electrical components. It is very hard to draw a real picture of a wire, bulb, switch, coil, battery, cell, etc. Therefore, symbols are used instead of drawing real images for the components while representing an electrical circuit. Symbols are easy to draw and understand quickly.

List of symbols:

Here is a list of Symbols representing the components of electrical circuits: connecting wires, switch in the ‘OFF’ position, bulb, cell, switch in the ‘ON’ position, and battery.
