1. Charge

   • Current means the flow of electric charge in a circuit (electrons). It is measured in amps.
   • Potential Difference/voltage means the push to move the current in a circuit.This is the driving force.
   • the resistance is any components in a circuit that reduces the flow of a current.
   • Charge is a measure of the rate of flow of current in a given time - Charge unit is Coulombs (C) and the unit is Seconds (s)
   • Q = I x T is the same as T = I x Q or I = Q/T
