Problem

A series R ⁣ ⁣ ⁣ ⁣ ⁣   LR\!\!\!\!\!\,\;L circuit is connected to a 50 Hz50\,\text{Hz} AC supply. The resistance is 100 Ω100\,\Omega and the inductance is 0.20 H0.20\,\text{H}. Determine the time by which the current maximum lags or leads the voltage maximum, and state the sense of the lag/lead. (a) Current lags voltage by 5.0 ms5.0\,\text{ms} (b) Current leads voltage by 1.8 ms1.8\,\text{ms} (c) Current lags voltage by 1.8 ms1.8\,\text{ms} (d) Current lags voltage by 3.2 ms3.2\,\text{ms}
