capacitance
Electrical storage property
Capacitance is the ability of a system to store electric charge.
In electronics, it measures how much charge a capacitor can hold at a given voltage—higher capacitance means more storage.
The unit is the farad.
Capacitance also appears in biological systems, where cell membranes act as tiny capacitors.
