The circuit has been connected as shown in the figure for a “long” time.
What is the magnitude of the electric potential across the capacitor?
Answer in units of V.
Homework Equations
Kirchoff's rules
[tex]V = IR[/tex]
[tex]V(t) = V_{0} e^{-t/\tau}[/tex]
[tex]C = \frac{Q}{C}[/tex]
[tex]Q(t) = Q_{f}(1-e^{-t/\tau)[/tex]
The Attempt at a Solution

That's how I redrew the circuit. But then I got confused. Does the capacitor short circuit the rest of the circuit (i.e., does no current flow in the 15 ohm and 48 ohm resistors)?
If not, I don't get what happens to (I - i1) and i1 once they get to the junction with the capacitor.
Help please?
