In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take ε = 10.0 V,R1 = 40.0 kΩ, R2 = 200 kΩ, and C = 13.0 μF.
(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.)
