Switches and outlets: places where electricity is delivered to appliances and devices

Wiring: the wires that carry power from the breaker box, to the outlets and switches

Electrical Circuits

Electrical circuits function by creating a loop that allows electricity to be transferred from the source to the appliance or device.

It is crucial to make sure that the wiring is installed and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.
