In an A.C. circuit power is dissipated in____________?
Correct answer: A. resistance only
- A. resistance only
- B. inductance only
- C. capacitance only
- D. none of the above
Explanation
Average AC power is dissipated in resistance, where energy is converted into heat. Ideal inductors and capacitors only store and return energy, giving zero average power consumption.
