Unformatted text preview: alancing 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). The quantity C = A is the capacitance and is measured in Farads (F), d hence q = Cv . The current, i, is the rate of charge flow, hence the dq capacitor equation: i = qt = C dv . dt E1.1 Analysis of Circuits (2013-3717) Capacitors and Inductors: 9 – 2 / 12 Types of Capacitor 9: Capacitors and Inductors • Capacitors • Types of Capacitor • Inductors • Passive Components • Series and Parallel Capacitor symbol represents the two separated plates.
