Basic of Electricity

1.1.1 What is the definition of electricity ?

• the rate at which electrons flow past a point in a complete electrical circuit

• the flow of electron or electric current. It is an invisible form of energy that can be transferred into other form of energy

• The flow of charges in a conductor
