1. The problem statement, all variables and given/known data In the figure below the battery has an emf of 20 V and an internal resistance of 1. Assume there is a steady current flowing in the circuit. http://img48.imageshack.us/img48/9211/44724253.gif [Broken] Find the charge on the 4 μF capacitor. Answer in units of μC. 2. Relevant equations Q = CE 3. The attempt at a solution No time is given, so I can't use the equation for charge as a function of t. From the figure, Resistors 1 and 5 seem to be in series. The circuit can't be simplified further. But the charge on the capacitor can't be Q=CE since a current is still flowing. Can I have some advice on how to get started? I tried using Kirchhoff, but I didn't get anywhere. I think I have too many unknowns, not enough equations (am I wrong?) I'd be very grateful for any help.
