The capacitance for a parallel-plate capacitor is given by: c=ϵAdc=ϵAd where ε is the permittivity, A is the area of the capacitor plates (assuming both are the same size and shape), and d is the thickness of the dielectric.
For a parallel plate capacitor, the electric field intensity (E) between the plates can be calculated using the formula: E=σ/E0 =V/d σ= surface change density Force Experienced by any Plate of Capacitor Due to the electric field created between the plates of a capacitor, no force acts on the device itself.
• 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.

When a voltage difference (potential difference) is applied across a component or system, it refers to the capacity of that component or system to store an electric charge. The ratio of the magnitude of the charge (Q) held on one of the plates to the potential difference (V) between the plates is known as a capacitor’s capacitance (C):
