I'm a chemistry student and I'm trying to make a simple model for heat conduction,

using the analogy between heat conduction and electric conduction.

I already managed to draw the heat-current as a DC-circuit.

Now I want to make a V(t) (voltage in function of time) formula for the second capacitor.

But I don't know how to start. I understand the derivation of the V(t)-curve of a single DC RC-circuit,

but I don't know how to apply these principles on my circuit.

Any suggestions?

Best regards

Johan
