Unformatted text preview: ummary A capacitor is formed from two conducting plates separated by a thin insulating layer. If a current i ﬂows, positive change, q , will accumulate on the upper plate. To preserve charge neutrality, a balancing negative charge will be present on the lower plate. There will be a potential energy difference (or voltage v ) between the plates proportional to q . d v = A q where A is the area of the plates, d is their separation and is the permittivity of the insulating layer ( 0 = 8.85 pF/m for a vacuum).
