[amp_mcq option1=”The current is in phase with the voltage” option2=”The current lags behind the voltage by 90°” option3=”The current leads the voltage by 90°” option4=”The current can lead or lag by 90°” correct=”option2″]
The correct answer is: B. The current lags behind the voltage by 90°.
In a pure inductive circuit, the current lags behind the voltage by 90°. This is because the inductor stores energy in its magnetic field, and this energy takes time to build up. As a result, the current does not start to flow until after the voltage has been applied.
Option A is incorrect because the current is not in phase with the voltage. Option C is incorrect because the current does not lead the voltage. Option D is incorrect because the current can only lag behind the voltage by 90°.
