MCQ
For watt$-$less power in an $AC$ circuit the phase angle between the current and voltage is.
- A$0^{\circ}$
- ✓$90^{\circ}$
- C$45^{\circ}$
- DNot possible
✓
Answer
Correct option: B.
$90^{\circ}$
Watt$-$less power in an $AC$ circuit is basically power supposed to be generated by inductive and capacitive reactance and since they are not resistor they generate any heat, and these power wasted is called watt$-$less power and its phase angle is always $90^{\circ}$ as it has only capacitor and inductor.
