The farad is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units, equivalent to 1 coulomb per volt. It is named after the Engl
A 1-farad supercapacitor. The scale behind is in inches (top) and centimetres (bottom).

The ampere, often shortened to amp, is the unit of electric current in the International System of Units. One ampere is equal to 1 coulomb moving past a point per second. It is named after French math

…SI), equivalent to 1 coulomb per volt (C/V). It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg−1⋅m−2⋅s4⋅A2. The capacitance of a capacitor is one farad when one coulomb of charge changes the potential between the plates by one volt. Equally, one farad can…
