## Homework Statement

## Homework Equations

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 R

_{3}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.
