Draw the circuit diagram to represent the circuit shown in Fig.14.21.
"
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. | Component | Image | Symbol |
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:
