The SI unit of electric current. One ampere is equal to one coulomb per second.
Used by AQA, Edexcel and OCR
Specification 4.2.1.2 · Paper 1
The unit of electric current. One ampere means that one coulomb of charge passes a point each second.
Revise: Electrical charge and currentTime must be in seconds when using amperes and coulombs.
Specification 10.7, 10.8, 10.9 · Paper 2
The unit of electric current, with symbol A; it is also called an amp.
Do not confuse units: current is measured in amperes (A), whereas potential difference is measured in volts (V).
Use for the symbol for current and A for its unit, the ampere.
If current is given in milliamperes, convert it to amperes by dividing by 1000 before using the equation.

Current describes the rate at which electric charge flows through a circuit. Its unit is the ampere, usually shortened to amp, and its unit symbol is A.
The unit of electric current; one ampere means one coulomb of charge passes a point each second.
