  1. Mar 25, 2010 #1
    1. The problem statement, all variables and given/known data
    In the figure below, R1 = 5.0 k, R2 = 10.0 k, C = 0.600 µF, and the ideal battery has emf script e = 20.0 V. First, the switch is closed a long time so that the steady state is reached. Then the switch is opened at time t = 0. What is the current in resistor 2 at t = 4.00 ms?
