At any point, the electrostatic potential is the amount of work done in bringing a unit positive test charge from infinity to that point in an electric field. It is done without acceleration. It is denoted by V and it is a scalar quantity.
? =? /Q
where? is the work done and q is the test charge.
The electrostatic potential helps in quantifying the energy configuration of charges. The unit is volt (V), where 1 V = 1 J/C.

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.
