Capacitance of a Capacitor
A larger plate area produces a larger capacitance and a smaller capacitance g(a) shows that the plate area of a parallel plate capacitor is the area of one of the plates. If the plates are moved in relation to each other, as shown in fig(b), the overlapping area determines the effective plate area.
