In the field of physics, the Farad (often denoted by the symbol ‘F’) can be defined as the unit of electrical capacitance. It provides a means to measure the ability of a substance to store electric charges. As per the International System of Units (often abbreviated to SI), one Farad is equal to the capacitance across which there is a potential difference of one volt when it is charged with one coulomb. Alternately, the Farad can be defined as the capacitance that stores a charge of one coulomb across a voltage (or electric potential difference) having a magnitude of one volt. The SI unit of electrical capacitance is named after the English scientist Michael Faraday. The SI base units of the farad are s4.A2.m-2.kg-1. It can be noted that the values of most capacitors are expressed in farads, microfarads, and nanofarads (also picofarads in some cases).
