Question
In the figure, C= 0.4 µF, E = 20 V, R1 = 10 k2, and R2 = 15 k2. Initially, the
switch S is closed a long time so that the steady state is reached. Then S is
opened at time t 0. Find:
(a) the potential difference across the capacitor in the steady state situation.
(b) the potential difference across R2 at t 4 ms after S is opened.
(c) the current in R2 at t 4 ms after S is opened.
