8.1 ECE 2300 – CIRCUIT ANALYSIS HOMEWORK #8 1. The switch in the circuit below was in position a for a long time, and then moved to position b at t = 0. a) Find i X (50[ms]). b) Find i Q (50[ms]). + - v S2 = 5[V] 5.6[k ] 3.3[k ] 22[k ] i X v S3 = 1[k ] i Q + - C X = 10[ F] 1.5[k ] a b 4.7[k ] - v S1 = 12[V] i S1 = 7 i X t = 0 i Q 2) For the circuit shown below, switches SW1 and SW2 have been in position a for a long time. At t = 0, both switches are moved instantaneously and simultaneously to position b and remain there. a) Find the power delivered by the v S2 voltage source, as a function of time, for t > 0. b) Calculate the numerical value of the total energy stored in the capacitors at t =  R 2 = 5[k ] + - v S2 = 200[V] + v S1 = 100[V] R 1 = 10[k ] t = 0 a b C 1 = 3[ F] R 3 = 40[k ] t = 0 a C 2 = 2[ F] SW2 SW1 b
