The generator voltage varies in time as $E(t)=V_a-V_b=E_{m}sin(t),$ where $E_m=120V$ and $=455ra\frac{d}{s}.$ The current varies in time as $I(t)=I_{m}sin(t-).$ The inductance is $L=300mH.$ The values for the capacitance $C,$ the resistance $R,$ and the peak current $I_m$ are unkown. What is known is that the current in the circuit leads the voltage across the generator by $||=57\mathrm{.}0$ and the average power delivered to the circuit by the generator is $P_{\text{a}\text{v}\text{g}}=70\mathrm{.}0W.$
