1. The problem statement, all variables and given/known data Three resistors, three capacitors, a battery, and two switches are connected in the circuit shown below. The values of all circuit elements are given in the figure. Originally, the switches S1 andS2 are open (as shown) and all of the capacitors are uncharged. At time t = 0, both switches are closed. http://online.physics.uiuc.edu/cgi/courses/shell/common/showme.pl?courses/phys212/oldexams/exam2/fa06/fig17.gif [Broken] What is the current through resistor R1 immediately after the switches are closed? 2. Relevant equations 3. The attempt at a solution Immediately (t=0) after the switches are closed, the capacitors should be uncharged. So they acts like wires. They have no V, that means there is no V across R3 as well since they are in parallel. So I redrew the circuit, having only the battery, R1 and R2 in series. And solve for the current, and that should be the current through R1. 9 V / (R1 + R2) = I1 But this isn't the answer apparently.
