Explanation:
Detailed explanation-1: -In SI units, we measure charge in Coulombs and potential in Volts, so the unit of capacitance is the Coulomb/Volt. This combination is given a special name: the Farad, or F. In cgs units, we measure charge in esu and potential in esu/cm. The unit of capacitance is thus just the centimeter!
Detailed explanation-2: -The unit for the farad is coulombs per volt (C/V). This describes a case of two oppositely charge plates, each with a coulomb of charge, and a potential difference of one volt between them. A farad is a large capacitance for most capacitors.
