27. Three incandescent bullbs of 100W each are connected in series in an
electric circuit. In anoter circuit another set of three bulls of same Wattage
are connected in parallel to the same source
a) Will the bulb in two circuits glow with the same brightness ? Justify your
continue to glow in each circuit?
Answers
Answer:
no because in series every bulb take current according to their capacity and in parallel current goes in each bulb will be equal
Answer:
(a) Will the bulb in the two circuits glow with the same brightness? Justify your answer.
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) Now let one bulb in both the circuits get fused. Will the rest of the bulbs continue to glow in each circuit? Give reason.
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.
