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 = 255 Ω, a capacitor of capacitance C = 6.2×10−6F, and
an inductor of inductance L.
(a) What must be the value of L for the phase angle Φ to be
zero?
(b) When L has the value calculated in (a), what is the current
amplitude in the circuit?
