Posted by Local Electrician Bayswater on 12 Mar 2026

Electricity is an essential component of our daily lives, powering everything from the lights of your homes, to appliances we use every day.  However, electricity systems are a bit complicated making it difficult to understand how they work can be difficult. In this guide we’ll breakdown the elements that make up an electric system, and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

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

Breaker box: the main source of electrical power in homes in which the power is split into various circuits

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

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

Electrical appliances and devices: the appliances and devices that require electricity to function.

Electrical Circuits

The term "electrical circuit" refers to one that allows electricity to flow from the main source (the breaker box) to appliances and devices within the home. There are two types of electrical circuits found in the home that are 120-volt and circuits with 240-volt voltage. 120-volt circuits are used for most household devices and appliances, whereas the 240-volt circuits are utilized to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by creating the loop which allows electricity to be transferred from the source to the appliance or device. The loop consists of a hot wire that carries the electricity along with a neutral wire that completes the circuit and a ground wire that provides the pathway for electricity to reach the ground in case of a fault.

Understanding Electrical Wiring

Electrical wiring comes in several kinds, such as non-metallic sheathed cables (NM), armored cable (AC), and conduit. Each type has its own advantages and disadvantages and the selection of the type of wiring is based on the specific needs of the installation.

The electricity travels through wires through a flow of electrons through the wire. Electrons move between the origin and the appliance or device and then back to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained in a correct manner, as defective wiring could lead to electrical hazards such as shocks or fires.

Common Electrical Problems

Some common electrical problems that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. These issues can be caused by a myriad of causes, including overloading circuits, broken connections, and defective wiring.

If you’re experiencing one of these problems, it’s essential to identify the source and take actions to rectify the issue. In certain instances, this may involve contacting an accredited electrician to look over and fix the wiring.
