831 A voltage vSt = 50 cos 5000t V is applied to the circuit in Figure P831.

8–31 A voltage vSðtÞ = 50 cos ð5000tÞ V is applied to the circuit in Figure P8–31.

(a) Convert the circuit into the phasor domain.

(b) Find the phasor current flowing through the circuit and the phasor voltages across the inductor and the resistor.

(c) Plot all three phasors from

(b) on a phasor diagram.
Describe if the current leads or lags the inductor voltage.
