(b) For the circuit shown in Figure Q3.2, the switch has been in the open position for a long time before moving instantaneously to the closed position at time t = 0 seconds. The current flowing into the circuit box labeled ???' is given by the following expression:
i x(t) = (1 - e^(-100t)) A for t ≥ 0
Determine what two different components are present inside the circuit block and explain each step used to obtain these.
