A parallel plate capacitor has a uniform electric field ' E ' in the space between the plates.
If the distance between the plates is ' d ' and the area of each plate is ' A ', the energy stored in the capacitor is: (ε₀ = permittivity of free space)

This chapter covers the concepts of potential, capacitors, and potential energy. It is considered as one of the easy chapter of the class 12 Physics.
It is the farad (F). The name came from Michael Faraday. SI Unit of Capacitance means the ability of a system to store an electric charge. One farad is the capacitance of a device that needs one coulomb of charge to provide one volt potential difference across it. Mathematically, it is represented by - 1 Farad = 1 Coulomb/Volt.
