Charge, Current and Potential Difference

CURRENT IS THE RATE OF FLOW OF CHARGE

Q = It   or    I = Q/t

where Q is the charge in Coulombs, I is the current and t is the amount of time taken

Conventional Currnet flows from + to - the opposite way from electrons

A COULOMB is the amount of charge that passes in one second when the current is 1 AMPERE

Current can be measured using an ammeter but the ammeter must always be attached in series. This is so that the Ammeter recieves the same current as the component
