For a basic RC circuit during charging:
q = CV(1-e-t/RC)
i = V/R (e-t/RC)
The Attempt at a Solution
I can solve basic RC circuits but this is just out of my realm of understanding. I can also find the max charge of the capacitor. I'm not looking for a full solution yet, I'm just hoping for someone to tell me if the best strategy is to:
1. Set up a lot of equation with Kirchoff's rules and solve a differential equation,
2. Use the fact that the current through R3 will increase from some minimum to to maximum exponentially (though I wouldn't know what the time constant would be), or
3. Use another strategy.
