Hello, I'm just doing a lab on the discharging of a capacitor.
The data collected shows that at first the current is large because the voltage is large, so charge is lost quickly and the voltage decreases rapidly. As charge is lost the voltage is reduced making the current smaller so the rate of discharging becomes progressively slower.
I'm just wondering how the fit equation A*exp(−Cx)+B relates to the equation for a discharging capacitor V = Vo e^-t/RC ?
