The capacitor recharge rate is a non-linear function—the rate at any given moment depends on how much energy is stored at that moment. Near zero and near full capacity, the recharge rate is very low, and it peaks at 25 percent. The important thing to remember is that the recharge rate declines dramatically once it falls below 25% of …

Capacitor
As the capacity of a capacitor decreases the voltage drop increases. It resists the current flow as it is charged up. The more water stretching the membrane, the harder it is to stretch further. The higher the capacitance leads to a higher capacity. A stretchier membrane allows for more water before it is done stretching.
