1) Determine the current in each resistor and charge on the capacitor after a long time immediately after the switch is closed
2) Determine the current in each resistor and charge on the capacitor after a long time
After the switch has been closed for a long time it is re-opened.
3) Determine the current in each resistor and the charge on the capacitor immediately after the switch has been re-opened.
4) Determine the time constant of the capacitor discharge.
V = I Req
Q = CV
The Attempt at a Solution
I got #1 and got I6 = 1A, I8 = 1.5A, and I12 = .5A
I'm not sure what to do about #2 though. What is the voltage across the capacitor? I thought it would be 6V, because that is the voltage across the parallel series. However, there is a voltage drop after the 1A current runs across the 6ohm resistor so the V across the capacitor is 0.
For #3 and 4, does the 8ohm resistor come into play or no?
Thanks for the help guys.
