Electrical Circuits

The term "electrical circuit" refers to one which allows electricity to flow from the point of origin (the breakers box) to the devices and appliances in the home.

Electrical circuits function by creating an electrical loop that allows power to flow from the source into the device or appliance. The loop consists of a hot wire which is the conduit for electricity and a neutral wire which completes the circuit, and a ground wire , which is an avenue for electricity to travel to the ground in case there is a problem.

The electricity travels through wires by creating a flow of electrons in the wire. The electrons flow through the wire from source, to appliance or device and then back to the source via the neutral wire. It is essential to ensure the wiring is installed and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.
