• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
When the plates are far apart the potential difference is maximum (because between the plates you travel through a larger distance of the field, and the field also isn't cancelled out by the field of the other plate), therefore the capacitance is less.
A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates. This is known as edge effects, and the non-uniform fields near the edge are called the fringing fields.
Explanation: Closer spacing results in a greater field force (voltage across the capacitor divided by the distance between the plates), which results in a greater field flux (charge collected on the plates) for any given voltage applied across the plates.

Two 2.60 cm x 2.60 cm plates that form a parallel-plate capacitor are charged to plus-minus 0.708 nC. (a) What is the electric field strength inside the capacitor if the spacing between the plates is
Capacitance is charge per EMF. Specifically Farads are Coulombs per volt. As you move the plates closer at the same applied voltage, the E field between them (Volts per meter) increases (Volts is the same, meters gets smaller). This stronger E field can hold more charges on the plates.
When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates. This result can be obtained easily for each plate. Therefore when we put …
If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease? The answers to these questions depends
To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.

Why is the electric field constant as the plates are separated? The reason why the electric field is a constant is the same reason why an infinite charged plate''s field is a constant.

A word about signs: The higher potential is always on the plate of the capacitor that has the positive charge. Note that Equation ref{17.1} is valid only for a parallel plate capacitor. Capacitors come in many different geometries and the formula for the capacitance of a capacitor with a different geometry will differ from this equation.
