1.AN A ELECTRIC CIRCUIT:

An electric circuit is a pathway for the flow of electrons.

1.1.PARTS OF AN ELECTRIC CIRCUIT:
Electric circuit consist of various parts:

• Generators provide the energy that electrons need in order to move.

cells and batteries:Electric current is generated by chemical processes.

• Loads are devides that transform electrical energy into other types of energy that we can use.

light bulbs:They produce light.

















motors:They produce movement.










resistors:They produce heat.










BELLS:They produce sound.

• SWITCHING DEVIDES are used to direct and interrupt the flow of electric current.

Switches,push butttons,3 way switches.
