Question

13. The power factor angle of a purely inductive circuit
is:
90 degree
45 degree
O 60 degree
O 75 degrees​

Answer 1

Answer:

In a pure inductive circuit, the current is lagging by 90 degrees from the voltage. The power factor is the cosine of the angle between the voltage and the current. If the angle between the voltage and current is 90, then cos90=0. Hence, the power factor is zero.
