Problem

A series circuit has

R = 50\,\Omega

L = 0.20\,\text{H}

and

C = 50\,\mu\text{F}

. If the supply frequency is raised from

50\,\text{Hz}

100\,\text{Hz}

while the rms voltage is kept the same, will the rms current increase, decrease or remain nearly the same? Give a brief reason for your answer.
