An AC circuit contains only an inductor. Which of the following is correct?1. The voltage lags the current by 180?.2. The current and voltage are in phase.3. The voltage lags the current by 90?.4. The current lags the voltage by 90?.5. The current lags the voltage by 180?.
the current lags the voltage by 180 degrees if it is a pure inductor. if the inductor is not pure one then the current lags voltage by 0deg to 180deg.
