(15 points) For the circuit shown, write the differential equation for in terms of the voltage across the capacitor:IUPUI ECE 204 Spring 2013 EXAM #2A Name: 2 2. (15 points) For the circuit shown, . The switch has been open for a long time and it closes at . Find the following: a) The current through the inductor just before and just after the switch is closed. b) The voltage across the inductor just before and just after the switch is closed. c) The final value of the current through the inductor after the switch has been closed for a long time. Remember: The current through the inductor does not change simultaneously but the voltage across the inductor can.IUPUI ECE 204 Spring 2013 EXAM #2A Name: 3 3.
