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.
