An AC circuit with a (240-mathrm{V}) peak emf has a (30.0-Omega) resistor connected in series to a

Question:

An AC circuit with a $240-\mathrm{V}$ peak emf has a $30.0-\Omega$ resistor connected in series to a capacitor for which the capacitive reactance is $X_{C}=60.0 \Omega$.

(a) What is the phase constant?

(b) What is the average rate at which energy is dissipated in the circuit?

(c) If the resistance in the circuit is $20.0 \Omega$, what would the capacitive reactance have to be in order for the power factor to be 0.15 ?
