[4 marks) Given the circuit below, assume that the switch has been in position 1 for along period of time. At t = 0, the switch moves to position 2. Calculate i(t) for t > 0. 1 6m i(t) 2. (6 marks) Consider the circuit below (Figure 2.a). The initial condition (i.e. t < 0) is that there is no energy stored in the capacitor. The input function is the voltage pulse shown in Figure 2.13.
