Three bulbs each having power pare connected in series in an electric circuit in another circuit another set of three bulbs of same power are connected in parallel to the same source, will the bulbs in both the circuits glow with the same brightness justify your answer
Answers
Answer:
Because in parallel circuit each appliance gets individual supply of 220 volt,whereas in series circuit,the voltage is divided between the appliances.Thus the appliances do not glow with their rated voltage.The current flowing through the appliances in series will decrease with increase in appliances because it will increase the resistance in the circuit
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) 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.
