A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as ε =Va - Vb = εmsinωt, where εm = 120 V and ω = 312 radians/second. The inductance L = 282 mH. The values for the capacitance C and the resistance R are unkown. What is known is that the current in the circuit leads the voltage across the generator by φ = 44 degrees and the average power delivered to the circuit by the generator is Pavg = 75 W.

Question
A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as ε =Va - Vb = εmsinωt, where εm = 120 V and ω = 312 radians/second. The inductance L = 282 mH. The values for the capacitance C and the resistance R are unkown. What is known is that the current in the circuit leads the voltage across the generator by φ = 44 degrees and the average power delivered to the circuit by the generator is Pavg = 75 W.
What is Imax, the amplitude of the current oscillations in the circuit?
What is R, the value of the resistance of the circuit?
What is C, the value of the capacitance of the circuit?
