Basic Definitions: Current
• The movement or the flow of electrons (charge) is referred
to as current.
• Current is represented by the letter symbol I ( it stands for
“intensity”).
• Current is the rate of flow of electrons through a conductor.
The basic unit in which current is measured is the ampere (A).
– One ampere of current is defined as the movement of
one coulomb ( quantity of charge) past any point of a
conductor during one second of time.
• An instrument called an ammeter is used to measure
current flow in a circuit.
