The unit of electrical charge is a measure of the amount of electric charge in a given system. The term 'coulomb' (7 letters) is used to describe the unit of electrical charge, and is named after French physicist Charles-Augustin de Coulomb. The term 'abcoulomb' (9 letters) is also used to describe the unit of electrical charge, and is an acronym for 'absolute coulomb'. The term 'faraday' (7 letters) is also used to describe the unit of electrical charge, and is named after English chemist and physicist Michael Faraday.
