Elec. that property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, equal to the ratio of the charge stored to the potential difference and measured in farads: abbrev. C
capacit(y) + -ance
See capacitance in American Heritage Dictionary 4
Symbol C The ratio of charge to potential on an electrically charged, isolated conductor.
Symbol C The ratio of the electric charge transferred from one to the other of a pair of conductors to the resulting potential difference between them.
a. The property of a circuit element that permits it to store charge.
b. The part of the circuit exhibiting capacitance.
