(c) A 10V voltage source has a series source resistor of 32 that is connected to a switch. The other teminal of the switch is connected to parallel combination of a 92 resistor and 42 resistor. The 42 resistor is in turn connected to a 40mF capacitor. If the switch is closed for a long time (t < 0) and is then opened at t 0, sketch the circuit diagram and find the following: (i) voltage across the capacitor at time t 2 0. (ii) initial energy (t = 0) and final energy (t> 0) stored in the capacitor.
