Question

Current in the circuit is wattles if
A. Current is alternating
B. Resistance in circuit is zero
C. Inductance in circuit is zero
D. Resistance and inductance both are zero

Answer 1

Answer:

This is because,in both inductive and capacitive circuits,the voltage and current differ by a phase angle of 90. ... The current in an AC circuit is said to be Wattless Current when the average power consumed in such circuit corresponds to Zero. Such current is also called as Idle Current.

Option B is your answer...

Explanation:

please mark me brainlist I will follow you.....

Answer 2

Answer:

B.

resistance in the circuit is zero

It is also known as the idle current as the average power consumed in the circuit is zero

this can tale place only in purely capacitative or inductive circuit only.It is because in such cases,the difference between the phase angle of cirrent and voltage is 90 degrees and so average
