coefficient of capacitance

coefficient of capacitance

[¦kō·ə′fish·ənt əv kə′pas·ə·təns]
(electricity)
One of the coefficients which appears in the linear equations giving the charges on a set of conductors in terms of the potentials of the conductors; a coefficient is equal to the ratio of the charge on a given conductor to the potential of the same conductor when the potentials of all the other conductors are 0.
