Question:

A 100-mH inductor is connected in parallel with a 2-kΩ resistor. The current through the inductor is i(t) = 50e-400t mA.
(a) Find the voltage vL across the inductor.
(b) Find the voltage vR across the resistor.
(c) Is VR(t) + VL (t) = 0?
(d) Calculate the energy in the inductor at t = 0.
