Question

For watt-less power in an $AC$ circuit the phase angle between the current and voltage is

• A. $0^o$
• B. ${90}^o$
• C. ${45}^o$
• D. Not possible

Answer 1

The correct option is B ${90}^o$

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 ${90}^o$ as it has only capacitor and inductor.
