Question

The true power used or consumed in a purely inductive circuit is zero watts. True or False

Answer 1

true

Step-by-step explanation:

As explained above, if current and voltage are 90° out of phase from each other like in pure inductive circuit, the total power of the circuit would be 0 as follow. This shows that in case of pure inductive circuit, the total power of the circuit would have zero as Cos 90° = 0.
