Given:
The bulb does not glow in the arrangement shown in Fig. 12.13.
To do:
To explain why the bulb would not glow in the arrangement shown in Fig. 12.13.
Solution:
Observation:
Let us observe the given circuit in fig. 12.13. The following components are used here in the given circuit.
1. Electric cell$\rightarrow$for power supply.
2. Wire$\rightarrow$for conduction of electric current.
3. A screwdriver$\rightarrow$for connecting wires.
4. An electric bulb$\rightarrow$Not glowing.
Reasons for not glowing the bulb
- In the given circuit, a screwdriver is used to connect both ends of the connecting wire.
- The handle of the screwdriver is made up of plastic.
- Plastic is an insulating material that prevents the current to pass through the circuit.
- The circuit is incomplete due to the handle of the screwdriver and no current is flowing through the circuit.
- If there is no current flowing through the circuit, then the bulb will not glow in the given figure.
