1. Consider the circuit below. Assume the switch has been in its initial position for a long time, and it switches position as indicated at t = 0. a. Find v(t) for all t > 0. b. Sketch v(t) as voltage vs. time; annotate critical values on your sketch. c. How much energy is stored in the capacitor at t = 0? www 50 ΚΩ (+1 12 V t = 0 100 ΚΩ M 100 μF + v(t)
