Problem

A series

R\!\!\!\!\!\,\;L

circuit is connected to a

50\,\text{Hz}

AC supply. The resistance is

100\,\Omega

and the inductance is

0.20\,\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\,\text{ms}

b) Current leads voltage by

1.8\,\text{ms}

c) Current lags voltage by

1.8\,\text{ms}

d) Current lags voltage by

3.2\,\text{ms}
