Question

Power Factor (Cos 0) = ?​

Answer 1

Answer:

We have also seen that in an AC circuit, the quantity cos(Φ) is called the power factor. ... When the power factor equals zero (0), the phase angle between the current and the voltage will be 90o as: cos-1(0) = 90o. In this case the actual power consumed by the AC circuit is zero regardless of the circuit current.
