Question

In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take  = 10.0 V, R1 = 57.0 kΩ, R2 = 120 kΩ, and C = 15.0 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.)
