Capacitance.
That property of a capacitor which deter-
mines how much charge can be stored in it for a given
potential difference between its terminals, measured in
farads, by the ratio of the charge stored to the potential
difference.

Capacitor.
A device consisting of two or more conducting
plates separated from one another by an insulating material
and used for storing an electrical charge. Sometimes called
a condenser.

Clipping.
Distortion of a signal by its being chopped off. An
overload problem caused by pushing an amplifier beyond
its capabilities. The flat-topped signal has high levels of
harmonic distortion which creates heat in a loudspeaker
and is the major cause of loudspeaker component failure.
