Next three questions: see the circuit below with a switch that was open for a long time, then closes at t = 0. Everything is the same as the first group except the location of the switch. V = 12 V, L = 5 H, R1 = 3 0, R2 = 5 0. S L V R2 Figure 2: Figure for Problems 4-6 4. Initial current through inductor (0.5 points) What is the current though the inductor at t = 0? 5. Steady state current through inductor (0.5 points) What is the current though the inductor at t = co? 6. Intermediate current through inductor (1 point) What is the current though the inductor at t = 0.5 s
