Concept

Problem: 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 = 737 radians/second. The values for the remaining circuit components are: R = 83 Ω, L = 112.5 mH, and C = 11.6μF.What is φ, the phase angle between the generator voltage and the current in this circuit. The phase φ is defined to be positive if the current leads the generator voltage, and negative otherwise.
