For the circuit in Figure B1.2 above, can you use superposition theorem/analysis to find i, and vo? If so, what are their values. [12 marks] In the circuit shown in Figure B2.1, the switch has been closed for a long time, before it is opened at t = 0. i) ii) iv) Find i, (t) for t < 0. For t 0, determine time constant of the circuit. Fort 20 determine i, (t) as a function of time. For t 0 find i, (t) and vo(t) as a function of time. 1-0 202 w OFF 20 A 0.1032 H 102400 Figure B2.1
