MCQ
For watt-less power in an AC circuit the phase angle between the current and voltage is.
  • A
    0°
  • B
    90°
  • C
    45°
  • D
    Not possible
✓

Answer

  1. 90°

Explanation:

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 90o as it has only capacitor and inductor.
