GCSE Physics · key term
The SI unit of electric charge. One coulomb passes a point when a current of one ampere flows for one second.
Used by AQA, Edexcel and OCR
Specification 4.2.1.2 · Paper 1
The unit of electrical charge. One coulomb passes a point when a current of one ampere flows for one second.
Revise: Electrical charge and currentTime must be in seconds when using amperes and coulombs.
Specification 10.5, 10.6, 10.9 · Paper 2
Do not describe voltage as an amount of energy: it is energy transferred for each coulomb of charge.
Convert quantities to joules, coulombs and volts before using the equation; for example, convert kilojoules to joules.

The unit of electric charge, with symbol C.
Across a lamp, for example, it tells us how much energy is transferred by each coulomb of charge passing through that lamp.
Specification P3.1g · Paper 1 (Foundation), Paper 3 (Higher)
The unit of electric charge. One coulomb passes a point each second when the current is one ampere.
Revise: Charge flow formulaThe standard combination is coulombs, amperes and seconds.
