An $L-R-C$ series circuit consists of a source with voltage amplitude 120 $\mathrm{V}$ and angular frequency $50.0 \mathrm{rad} / \mathrm{s},$ a resistor with $R=400 \Omega,$ an inductor with $L=9.00 \mathrm{H},$ and a capacitor with capacitance $C .$ (a) For what value of $C$ will the current amplitude
in the circuit be a maximum? (b) When $C$ has the value calculated in part (a), what is the amplitude of the voltage across the inductor?
