a. Find v(t) for all t > O.
b. Sketch v(t) as voltage vs. time; annotate critical values on your sketch.

2) Consider the circuit diagram below; assume the switch has been in the initial position for a long time, and it switches position as indicated at t = 0.

a. Find i(t) through the inductor for all t > 0.
b. Sketch i(t) as current vs. time; annotate critical values on your sketch.
c. How much energy is stored in the inductor at t = ∞?

3) Consider the circuit diagram below, and assume that the circuit is in steady state. Determine:
