Answer 1

Answer:

Will the bulb glow in the circuit shown in fig 12.6 ? Explain. Solution: No, the bulb will not glow in this circuit because the switch is open and the circuit is broken.

Answer 2

Answer:

If the bulbs are connected in parallel then the bulb will glow and in series then it will not glow.

Explanation:

Condition 1:

• If bulb A and B both are connected with the parallel connection then the bulb will glow if any one of them get fused.

Reason: In parallel connection both the bulb get separately connected with the cell and if any of them get fused, the circuit remains closed and the other bulb remains glowing.

Condition 2:

• If bulb A and B both are connected in series then the bulb will not glow if any one of them get fused.

Reason: In series, both bulbs are connected with the same wire and if any bulb gets fused then the circuit becomes open and the current stop flowing.
