This virtual experiment is part of Virtual Science's Virtual Physics Laboratory. It allows you to measure the rates of charging and discharging of a capacitor and determine the characteristic asymptotic shape of the curve by plotting the observed values. This is one of thirty experiments from the Virtual Physics Laboratory. This has gained the Association for Science Education's Green Tick of approval.
