Capacitance and Charge on a Capacitors Plates

Where A is the area of the plates in square metres, m 2 with the larger the area, the more charge the capacitor can store. d is the distance or separation between the two plates.. The smaller is this distance, the higher is the ability of the plates to store charge, since the -ve charge on the -Q charged plate has a greater effect on the +Q charged plate, resulting in more electrons being
