The phase difference between virtual voltage and virtual current for a wattless current will be:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 90°
In an AC circuit, wattless current refers to a situation when the average power dissipated in the circuit is zero.
And, when the phase difference between voltage and current is 90°, the power dissipated in the circuit is 0. $[\cos 90° =0]$
