1 Answer

Answer :

For many, electricity is a mystery. To understand a simple electric circuit that operates many useful appliances and devices, electricity must be understood. Electricity is the flow of electrons. Think of water flowing in a circular ditch with a pump or paddle wheel that keeps it flowing. The pump is what makes it flow. Electricity is the same way. The alternator, battery, or dynamo is what makes electrons flow. Think of the water in the ditch moving because of the pump that moves it. Think of the water moving a wheel that drives an axle to do some useful work, such as a grinder. Now think of a simple electric circuit such as a lamp. In order for the light to glow, there must be a flow of electrons. This is done by plugging the lamp into the wall and turning or pushing the switch to make t
