S SR RS An EMF : - 20 volts is connected in the circuit shown to two resistors R = 4 $2 and an inductor ( = 4 H. The switch is closed at time r = 0 (a) What is the current through point X immediately after the switch is closed? (b) What is the current through the battery immediately after the switch is closed? (c) How much energy is stored in the inductor a long time after the switch is closed
