Given:

A circuit shown in Fig.14.21.

To do:

To draw the circuit diagram to represent the circuit shown in Fig.14.21.

Solution:

Here we have to draw a circuit diagram for given a circuit in figure 14.21. Let us observe the given circuit and its components:

Observation of the circuit:

On observing the given circuit following components are found:

1. An electric Bulb: One end of the bulb is connected to the positive terminal of the cell and another is connected to the safety pin through a wire.

2. Electric cell: Positive terminal is connected with one end of bulb and and another one is connected to a fix point through connecting wires.

3. Connecting wires: Green wire is connecting one end of the bulb to the safety pin and red wires are connecting both the terminals of cell to bulb and fix point.

4. A safety pin: Used as a switch.

On observing the given circuit we get to know that one end of the safety pin is connected to one of the terminal of the bulb through the connecting wire$(green)$ and another end is away from the red wire that is connected to the negative terminal of the electric cell. So it is a switch 'OFF' position. There is no current flowing through the circuit and the bulb is not glowing. To draw a circuit diagram for the given circuit let us know a little bit of the symbols of the components of the circuit:

Symbols of the circuit components:

Let us see the following table that shows the symbols used for the components:

S/no.ComponentImageSymbol
1.Connecting wires



2.Switch in 'OFF' position



3.Bulb



4.Cell



Drawing a circuit diagram for the given circuit:

From the observation of the given circuit let us draw a circuit diagram by using the symbols of the components. The diagram for the given circuit is as below:
