Posted by Adelaide Electricians on 24 Jan 2026

Electricity is an essential component of our lives, powering everything from the lighting in your homes, to gadgets we use on a daily basis.  But electrical systems can be a bit complicated making it difficult to understand how they function can be difficult. In this guide, we’ll break down the elements in an electrical circuit and describe how circuits function to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

A home’s electrical system includes a number of essential components that work to provide power throughout homes. This includes:

Breaker box is the central distribution point for electrical power in a home, where the electricity is divided into several circuits

Switches and outlets: the points where electricity is delivered to appliances and devices

Wiring: the electrical wires that transmit power 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 a pathway which allows electricity to flow from the point of origin (the the breaker box) to the devices and appliances in the home. There are two kinds of electrical circuits found in a home which are 120-volt circuits and 240-volt circuits. 120-volt circuits are used for most household devices and appliances, whereas 240-volt circuits are used for larger appliances such as air conditioners and electric dryers.

Electrical circuits work by creating the loop which allows electricity to flow from the source into the device or appliance. The loop is comprised of a hot wire which carries the electricity along with a neutral wire that completes the circuit as well as a ground wire , which is a path for electricity to reach the ground in the event there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each type comes with its own pros and disadvantages and the selection of the wiring type is contingent upon the specific requirements of the installation.

The electricity travels through wires by creating a flow of electrons that travel through the wire. Electrons move through the wire from source, to appliance or device, and back to the source using the neutral wire. It is essential to ensure the wiring is installed and maintained properly, since improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found at home include tripping breakers, flickering lights, and electrical outlets that are not working. These problems can be caused by a variety of factors such as overloading circuits poor connections, or faulty wiring.

If you’re experiencing one of these problems, it’s crucial to pinpoint the cause and take appropriate steps to correct the issue. In certain instances it may be necessary to contact an accredited electrician to examine and fix the wiring.
