Charge

Definition

The quantity of electric charge transferred, measured in coulombs (C).

Used by Edexcel

Specification 10.9 · Paper 2

Electric current describes how quickly charge passes a point in a circuit. A larger current means that more charge passes each second.
Revise: Charge Equation

1
Do not confuse quantity symbols with unit symbols: charge is $Q$ and is measured in C; current is $I$ and is measured in A.
2
Check a rearrangement by considering the meaning: current is charge per second, so $I=Q/t$ .
