In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take E = 10.0 V, R, = 47.0 kn, R, = 200 kn, and C = 14.0 µF. R1 R2 (a) Determine the time constant before the switch is closed. (b) Determine the time constant after the switch is closed. (c) Let the switch be closed at t = 0. Determine the current in the switch as a function of time. (Assume I is in A and t is in s. Do not enter units in your expression. Use the following as necessary: t.)
