A resistor and a capacitor are connected to an AC supply of 200 volt, 50 Hz in series. The current in the circuit is 2 ampere. If the power consumed in the circuit is 100 watt, then the resistance in the circuit is:
A
100 Ω Ω
B
25 Ω Ω
C
D
400 Ω Ω
Text Solution
Verified by ExpertsThe correct answer is:
B
In an ac circuit capacitor does not consume any power. Therefore, power is cosumed by the resistor only.
