Power Factor — Pure ResistorEasyQuestion 20229

Question

Power factor of a circuit containing only a resistor is:
  1. A
    0
  2. B
    0.5
  3. C
    1/√2
  4. D
    1
    Correct

Correct answer

1

Explanation

For a pure resistor, voltage and current are in phase (φ = 0°). Power factor = cos 0° = 1. All power is absorbed and dissipated as heat.
