The capacitance describes how much charge can be stored on one plate of a capacitor for a given "push" (voltage drop). A very stretchy, flexible membrane corresponds to a higher capacitance than a stiff membrane. A charged-up capacitor is storing potential energy, analogously to a stretched membrane.

A new linear capacitor model is proposed. It is based on Curie''s empirical law of 1889 which states that the current through a capacitor is i(t)=U/sub 0//(h/sub 1/t/sup n/), where h/sub 1/ and n are constants, U/sub 0/ is the dc voltage applied at t=0, and 0<n<1. It implies that the insulation resistance is R/sub i/(t)=h/sub 1/t/sup n/, that is, it increases almost in proportion to time since ...
