The power dissipated in a pure capacitor is______________?
Correct answer: A. zero
- A. zero
- B. proportional to applied voltage
- C. proportional to value of capacitance
- D. both (B) and (C) above
Explanation
A pure capacitor stores and returns energy but does not consume average real power, because its current leads voltage by 90°. Its instantaneous power alternates between positive and negative, giving zero net dissipation.
