Problem

In a series circuit with

R = 2\,\Omega

L = 0.50\,\text{H}

and

C = 5.0\,\mu\text{F}

, the supply frequency is

150\,\text{Hz}

. Which option best describes the phase relationship between current and source voltage? a) Current leads almost

90^\circ

ahead of the voltage b) Current lags about

45^\circ

behind the voltage c) Current lags almost

90^\circ

behind the voltage d) Current is almost in phase with the voltage (phase angle

\approx0^\circ

)
