Questions
A resistor and a capacitor are connected to an ac supply of 200V, 50Hz in series. The current in the circuit is 2A. if the power consumed in the circuit is 100 watt, then the resistance in the circuit is
detailed solution
Correct option is B
In an ac circuit, pure capacitor does not consume any power. Therefore, power is consumed by the resistor only. ∴P=I2vR Or 100=(2)2R Or R=25ΩTalk to our academic expert!
