A Series Circuit Consists of an Ac Voltage Source of Frequency

Short Answer

A series circuit consists of an ac voltage source of frequency $60 \mathrm {~Hz}$ and source voltage amplitude $345 \mathrm {~V}$ , a resistor of resistance $393 \Omega$ , a capacitor of capacitance $2.7 \times 10 ^ { - 6 } \mathrm {~F}$ , and an inductor of inductance $L$ .
(a) What must be the value of $L$ for the phase angle of the circuit to be zero?
(b) When $L$ has the value calculated in part (a), what is the current amplitude in the circuit?
