Re: Capacitance
Capacitance is \[\epsilon A/d\] where \[\epsilon\] is permittivity of the dielectric material, \[A\] is the cross sectional area where the E-field lines cross and \[d\] is the distance between the plates. If fringing is taken into account, the effective cross-sectional area which the E-field crosses is larger than the cross-sectional area of the plates themselves. So the effective cross-sectional area in the capacitance equation is larger and therefore capacitance is larger. Does that help you out?
