Question

three incandescent bulb of hundred watt each are connected in series in an electric circuit in another circuit another set of 3 bulb of the same voltage are connected in parallel to the same source will the bulb in the two circuit glow with the same brightness justify your answer ​

Answer 1

Explanation:

No, though the bulbs are of same wattage they glow with different brightness if they are connected in series and parallel. If one bulb in both the circuits get fused rest of the bulbs continue glowing as the current is passed through them.

Answer 2

Answer:

(a)

Ans. Voltage gets divided in series combination. So bulbs in series combination will glow with less brightness. Voltage does not get divided in parallel combination, so bulbs in parallel combination will glow with more brightness.

(b)

Ans. In case of series combination, fault in even a single component will break the circuit.

So, when one of the bulbs gets fused: another bulb would continue to glow.
