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?
