Physics

A circuit is constructed with an AC generator, a resistor,capacitor and inductor as shown. The generator voltage varies intime as ε =Va - Vb = εmsinωt,where εm = 120 V and ω = 231 radians/second. Theinductance L = 155 mH. The values for the capacitance C and theresistance R are unkown. What is known is that the current in thecircuit leads the voltage across the generator by φ = 49 degreesand the average power delivered to the circuit by the generator isPavg = 106 W.

What is Imax, the amplitude of the currentoscillations 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?

The value of ω is now changed, keeping all other circuitparameters constant, until resonance is reached. How was ωchanged?

ω was decreased

ω was increased

What is the average power delivered to the circuit when it is inresonance?
