Hello, I have been pondering how to plot the instantaneous rate of change of one capacitor into another through a resistive impedance R. So for example you would have C1=1 farad (100volts) C2= 10 Farad (Zero volts) R1 = 100ohms So one would have Capacitor 1 at 100 volts, discharge through R of 100 ohms into capacitor 2 of zero volts, and 10 farads. When the process has settled to equilibrium, there will be 9.09 volts on each capacitor, after X time. I would like to know how long it takes to reach equilibrium, and would think that normal time constants will not quite apply, because the capacitor is not discharging into a resistance only, but into another capacitor through a resistance, therefore you have a static impedance (R1) and a changing impedance (C2). So what would this discharge graph look like? What would be the function? How long would it take to reach equilibrium at 9.09 volts on each capacitor? If someone would be willing to explain this to me I would be very grateful!
