Question

In a purely inductive circuit, the power factor is

(A) 0

(B) 1

(C) 0.5

(D) infinity

Answer 1

Correct option is : (A) 0

The power in a purely inductive circuit is given by:

\(P = VI\cos\theta\)

where P = Active power

V = Voltage

I = Current

\(\cos\theta = \) Power factor

\(\because\cos\theta = 0\)

\(\therefore\ P = VI\times (0)\)

P = 0

Answer 2

Correct option is (A) 0
