Please answer all of the following:

15) For the circuit in Figure 7, the switch has been open for a long time. At 0, it suddenly closes. Determine the initial voltage on the capacitor, vc(0). Define the capacitor voltage such that the positive terminal on top of the device. 2 H L 00 15 mA 40 3 5 mF Figure 7 a) (0) 0 b) (0) 0.6(V) c) e(0') 1.25(V d) (0) 0.4(V) e) None of the above 16 the inductor, diu0'dt the time derivative of the current in Figure 7, what is the initial value di,(00.5 A/s a di di (0)02 A/s b) di di, (0) c) dr di, 25 Als d) None of the above For the circuit of Figure 7, identify the correct general expression for i) for 0. 17 a) ,(t)15-e10cos(9.68t)-18.08 sin(9.681)] mA b) i(t)15-e-15.13 cos(9.68) +9.61 sin(9.68)] mA c) 4(0)- 7.5-e 14.25 cos(9.681)-26.55 sin(9.681)] ma d) i)10-ecos(9.680)] mA None of the above
