Answer:
The correct answer is (b) Resistance in the circuit is zero.
Explanation:
It is also known as the idle current as the average power consumed in the circuit is zero.
This can take place only in purely capacitative or inductive circuit only. It is because in such cases, the difference between the phase angle of current and voltage is 90° and so average power also becomes zero( as it depends on the cos component ).
