In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take Ɛ = 10.0 V, R₁ = 50.0 ΚΩ, 2 185 kn, and C = 10.0 μF. R₁ w www R2 (a) Determine the time constant before the switch is closed. S (b) Determine the time constant after the switch is closed. S (c) Let the switch be closed at t = 0. Determine the current in the switch as a function of time. (Use the following as necessary: t. Express your answer in units of μA.) I(t) = =
