# Capacitor-Resistor-Capacitor Circuit Equation

Looking for an equation to describe the voltage level on each of two capacitors versus time. Each capacitor has a "bleed" resistor across it. First capacitor charged to 10 volts. A switch close connecting the first capacitor (C1) to a second capacitor (C2) through a resistor (R1). Can anyone provide either:
1. Equation desired.
2. Source material containing equation desired.

Thanks!

correct me if i'm wrong, but i feel you are missing something else here, like is the circuit a series or parallel or series-parallel circuit?

perhaps above link may be of some help?

or perhaps this other site?

I tried to post an image, unsuccessfully. The lower plate of each capacitor is tied to ground. Each capacitor has a shunt resistor across it. The two capacitors are connected through a switch and a resistor. First capacitor is fully charged, then the connecting switch is closed transferring charge from the first capacitor to the second through the series resistor.
