Examples from the Web for capacitance
The capacitance of a condenser or a circuit depends on its size and form and the voltage of the current that is charging it.
The variable condenser used in series with the aerial wire system has 26 plates and is equal to a capacitance of .0008 mfd.
The condenser used in the secondary coil circuit has 14 plates and this is equal to a capacitance of .0004 mfd.
In honeycomb and other stagger wound coils the capacitance is more evenly distributed.
As the blades of the tuning forks vibrate, the capacitance is alternately increased and decreased by the required amount.LRL Accelerators

- the property of a system that enables it to store electric charge
- a measure of this, equal to the charge that must be added to such a system to raise its electrical potential by one unit

Word Origin and History for capacitance
Online Etymology Dictionary, © 2010 Douglas Harper
- A measure of the ability of a configuration of materials to store electric charge. In a capacitor, capacitance depends on the size of the plates, the type of insulator, and the amount of space between the plates. Most electrical components display capacitance to some degree; even the spaces between components of a circuit have a natural capacitance. Capacitance is measured in farads. Compare inductance.
