In an ideal inductive circuit, how does the current relate to the voltage in terms of phase difference?

Show Answers

The current and voltage peak simultaneouslyThe current lags the voltage by a quarter cycle (90 degrees)The current leads the voltage by a quarter cycle (90 degrees)The current may either lead or lag the voltage by 90 degreesNo phase difference exists between current and voltage

Explanation

In a purely inductive circuit, the current always lags behind the voltage by 90 degrees because the inductor opposes changes in current, causing the current waveform to reach its peak after the voltage waveform.
