Electrical circuits are the paths that allow current to flow around a loop.
Everything plugs into the outlet that is connected to the circuits in the walls of your home. These are connected to the neighborhood circuit and finally to the power company.

​Electrical Circuits

Power is the rate at which an electrical circuit transfers energy.

Scientists measure power in watts (w).

​

Power
