A series ac circuit consists of a voltage source of frequency f=60 Hz and source voltage amplitude 345 volts, a resistor of resistance R=335 ohms, a capacitor of capacitance C=9.6*10^-6 F, and an inductor of inductance L.
(a) what must be the value of L for the phase angle (phi) to be zero?
(b) when L has the value calculated in (a), what is the current amplitude in the circuit?
