RL Circuits

Q1: Total current in an RL circuit always lags the source voltage.

A True

B False

ANS:A - True

The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage.
