It's measured in coulombs, named for Charles-Augustin de Coulomb, and its SI unit is abbreviated as Q. Current is the motion of electrical charge from higher voltage to lower voltage. Completing ...

One ampere is the current that flows when one coulomb of charge passes a point in a circuit in one second. Key fact 'Amps' is an abbreviation for 'amperes', the unit for current (also abbreviated ...

per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per coulomb of charge.
