5. The switch in the circuit shown in Figure has been closed for a long time before it opens at time t = 0. Determine the values of ic(0-), the current in the capacitor immediately before the switch opens and ic(0+), the current in the capacitor immediately after the switch opens. t = 0 + 20 Vic (t)↓ 2.2 μF 20 Ω Figure
