Question

In the circuit below, the capacitor is initially uncharged and the switch S in the open position. ? = 20 V C = 15 ?F L = 2.0 H R1 = 10 ? S R2 = 20 ? (a) The switch is moved to position A at time t = 0. What is the voltage drop across the resistor R1 immediately after t = 0? (b) After a long time, what would be the voltage drop across the resistor R1? (c) Under the conditions stated in part (b), what would be the charge on the capacitor? (d) At an even later time, t = T, the switch is moved to position B. What is the voltage drop across the resistor R1 immediately after t = T? (e) Next, a long time after t = T, the current in R1 reaches a constant final value. Determine this final value of current. (f) Under conditions stated in (e), find the final energy stored in the inductor.
