Homework Statement
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.

Find the charge on the 4 μF capacitor.
Answer in units of μC.
Homework Equations
Q = CE
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.
