A 30 Q resistor and a 20 mH inductor are connected in parallel. This parallel combination is also in parallel with the series combination of a 40 Q resistor and a 20 µF capacitor. These three parallel branches are driven by a sinusoidal current source whose current is 140 sin (2500t +45°) A. a) Draw the frequency-domain equivalent circuit. b) Reference the voltage across the current source as a rise in the direction of the source current, and find the phasor voltage. c) Find the steady-state expression for v(t).
