The switch in Figure Q4 has been connected to position B for a long period of time. At t = 0, the switch is changed to position A. (a) Determine vc(t) and i(t) for t > 0. (12 marks) (b) Did the capacitor release or store energy during the transient? What is the amount of energy released/stored? (3 marks) (c) Did the inductor release or store energy during the transient? What is the amount of energy released/stored? (3 marks) 36 V 1000 uF 24 + vc(t) < Figure Q4 A At=0 B 90 92 iL(t) 480 mH 310
