Electricity is an essential component of our lives, powering everything from the lighting in your homes, to gadgets that we use each day.  But electricity systems are a bit complicated knowing how they function isn’t easy. In this article we’ll breakdown the elements in an electrical circuit, and describe how circuits function to power devices and appliances.

Components of an Electrical System

An electrical system is comprised of several essential components that work to provide power throughout a home. They include:

Breaker box is the central distribution point for electrical energy in a house that is where electricity is divided into several circuits

Switches and outlets: points at which electricity is supplied to devices and appliances

Wiring: the electrical wires that carry electricity from the breaker box to the outlets and switches

Electronic appliances and gadgets: the appliances and devices that require electricity to function.

Electrical Circuits

An electrical circuit is one that allows electricity to flow from the main source (the the breaker box) to the appliances and devices in the home. There are two types of electrical circuits found in the home: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized for the majority of household appliances and appliances, while the 240-volt circuits are utilized for larger appliances such as dryers and air conditioners.

Electrical circuits function by creating the loop which allows electricity to be transferred from the source to the device or appliance. The loop is made up of a hot wire that carries the electricity, a neutral wire that completes the circuit as well as a ground wire that provides the pathway for electricity to travel to the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each has its advantages and disadvantages, and the choice of the wiring type is contingent upon the particular requirements that the location requires.

Electricity travels through wiring by creating a flow of electrons that travel through the wire. The electrons travel between the origin and the device or appliance returning to the source using the neutral wire. It is essential to ensure the wiring is put in place and maintained properly, since improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Problems

Common electrical issues in homes include tripping light bulbs, flickering breakers and disconnected outlets. These issues can be caused by a myriad of causes such as overloading circuits loose connections, and faulty wiring.

If you’re experiencing any of these issues it’s crucial to pinpoint the source and take steps to correct the issue. In certain instances this could mean contacting a licensed electrician to inspect and repair the wiring.
