Power factor of the following circuit will be zero__________?
Correct answer: D. both B. and C.
- A. resistance
- B. inductance
- C. capacitance
- D. both B. and C.
Explanation
For a pure inductor or pure capacitor, the phase angle is 90°, so power factor cos 90° equals zero. A pure resistance has zero phase angle and therefore unity power factor.
