Pure inductive circuit takes power from the A.C. line when_________?
Correct answer: A. applied voltage decreases but current increases
- A. applied voltage decreases but current increases
- B. applied voltage increases but current decreases
- C. both applied voltage and current increase
- D. both applied voltage and current decrease
Explanation
In a pure inductor, current lags voltage by 90° and energy is returned during the remaining part of the cycle. The source supplies energy when voltage decreases while current increases, making option a correct.
