Problem

A signal generator provides a peak voltage of

10\,\text{V}

to a series RLC circuit that will be operated at its resonant frequency of

20\,\text{kHz}

. Determine the least resistance that must be included in the circuit so that the peak current at resonance does not exceed

0.20\,\text{A}
