The switch in the circuit has been in position a for a long time. At t=0 the switch is moved to position b. Part A Calculate the initial voltage on the capacitor if v = 180 V, and i = 2.7 mA . Express your answer with the appropriate units. ANSWER: vc (0+) = Part B Calculate the final voltage on the capacitor. Express your answer with the appropriate units. ANSWER: vc (00) = Part C Calculate the time constant for t > 0 Express your answer with the appropriate units. ANSWER: T = 3 kn 9 kn 20 nF 10 ΚΩ ww VC 40 ΚΩ Part D Calculate the length of time required for the capacitor voltage to reach zero after the switch is moved to position b. Express your answer with the appropriate units.
