Capacitor Basic Calculations
The smallest capacitor will therefore be the limiting factor. However, because each capacitor can hold a different capacity, the voltage of each capacitor will be different. We find the voltage of each capacitor using the formula voltage = charge (in coulombs) divided by capacity (in farads).
Are capacity and capacitance the same?
The material between the plates of any capacitor has a maximum electric field that it can tolerate before breaking down. And since the electric field between the plates is proportional to the charge on the plates, which is in turn proportional to the voltage applied, this means that most capacitors have a maximum voltage rating.
