A 40 H resistor, a 5 mH inductor, and a 1.25 uF capacitor are connected in series. The series-connected elements are energized by a sinusoidal voltage source whose voltage is 600 cos (8000^ + 20°)V.
a) Draw the frequency-domain equivalent circuit.
b) Reference the current in the direction of the voltage rise across the source, and find the phasor current.
c) Find the steady-state expression for i(t).
