1. The problem statement, all variables and given/known data The switch in the figure below has been in position a for a very long time. It is suddenly flipped to position b for 1.65 ms, then back to a. How much energy is dissipated by the 50 Ω resistor? (Assume = 65 V.) 2. Relevant equations ΔVloop = 0 Volts Q/V = C V = IR 3. The attempt at a solution I understand that if the 125 Ω resistor wasn't there, the capacitor would have the full 65 Volts across it, but there is a voltage drop across the 125 Ω resistor, so the capacitor has less than 65 Volts on it. I set up an equation starting from the bottom left corner of the circuit, 0 = 65 Volts - (125 Ω)*I - Q/(20μF), and I tried to solve it by bringing the Q/(20μF) to the other side and replacing I with V/R, but the V in V/R is the voltage across the resistor, not the battery's voltage. In short, I'm stuck.
