Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage across their plates. The capacitance of a capacitor is defined as the ratio of the maximum charge that can be stored in a capacitor to the applied voltage across its plates.
The parallel plate capacitor is the simplest form of capacitor. It can be constructed using two metal or metallised foil plates at a distance parallel to each other, with its capacitance value in Farads, being fixed by the surface area of the conductive plates and the distance of separation between them.
The simplest example of a capacitor consists of two conducting plates of area A , which are parallel to each other, and separated by a distance d, as shown in Figure 5.1.2.

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 ...

A flashing light is controlled by a charging and discharging of an RC circuit. If the light is flashing too rapidly, describe two changes that you could make to the ...
When the two capacitors are charged, they are constantly trying to come closer due to electrostatic forcd between them, when you displace the plates away from each other there is a net displacement in opposite direction to that of force, hence - work is done by the capacitor system or in other words the energy of this system increases which gets stored as electrostatic …

We know that both plates of a capacitor have the same charge because of the principle of charge conservation. When a capacitor is charged, electrons are transferred from one plate to the other, creating an equal but opposite charge on each plate. This ensures that the net charge of the system remains zero.

Charging a capacitor simply applies a voltage to both sides (i.e. it doesn''t add or remove charge), so the capacitor must remain net neutral. In other words, the two plates must store equal amounts of charge.
The two plates inside a capacitor are wired to two electrical connections on the outside called terminals, which are like thin metal legs you can hook into an electric circuit.
