The negative gradient of the electric potential is called an electric field. The electric field points in the direction of the steepest decrease of potential. The electric field is defined in a simpler terms as equal to the change in potential per unit displacement. The electric field is strong, if the potential decreases sharply over a small distance. The electric field can be calculated using this relationship if the potential distribution is known, and vice versa. It is important for the understanding of the energy transfer in electrostatics and charge dynamics.

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.
