AN ELECTRIC CIRCUIT

An electric circuit is a pathway for the flow of electrons, that is called electric current.


-Parts of an electric circuit:

• Generators provide the energy that electrons need in order to move. Examples: cells and batteries.

 

• Loads are devices that transform electrical energy into other types of energy that we can use. Examples: light bulbs, motors, resistors and bells.



• Switching devices are used to direct and interrupt the flow of electric current. Examples: switches, push buttons and 3-way switches.
