What is Charge?
The size of the current is the rate of flow of charge. Electrons are negatively charged particles which transfer energy through wires as electricity. Charge is measured in coulombs (C). Electrons are really small and the effect of one electron would be really difficult to measure, It is easier to measure the effect of a large number of electrons. One Coulomb of charge contains 6 × 1018 electrons.
Charge equation
To calculate Charge we use this equation.
$Q = { \mathit I \, \mathit t} $
