Problem

A series RLC circuit has

R = 30\,\Omega

L = 50\,\text{mH}

and

C = 20\,\mu\text{F}

. It is connected to an AC source of

150\,\text{V}

(rms). a. Calculate the current amplitude when the circuit is driven at

200\,\text{Hz}

. b. Calculate the current amplitude when the circuit is driven at

400\,\text{Hz}
