The maximum value of the current is expressed as:

i_{max} = ε_{m}/Z

A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as ε = V_{a} - V_{b} = ε_{m}sin(ωt), where ε_{m} = 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.

Given that the impedance of the circuit is Z = 89.7Ω, what is I_{max}, the magnitude of the maximum value of the current in the circuit?
