Posted by Electrician Adelaide SA on 6 Jul 2026

Electricity is a vital part of our everyday lives, supplying everything from the lights of our houses to appliances we use every day.  However, electric systems may be complicated, and understanding how they work can be challenging. In this guide we’ll breakdown the components in an electrical circuit, and explain how circuits work to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

A home’s electrical system includes a number of important components that work to deliver power throughout the home. They include:

Breaker box: the central distribution point for electrical energy in a house, where the electricity is divided into different circuits

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

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

Electric appliances, devices and equipment: appliances and devices that require electricity to function.

Electrical Circuits

An electrical circuit is one which allows electricity to flow from the main source (the breakers box) to the appliances and devices in the home. There are two kinds of electrical circuits that can be found in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed to power most household appliances and appliances, while the 240-volt circuits are designed to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by completing an electrical loop that allows power to flow from the source to the device or appliance. The loop is comprised of a hot cable that transports the power and a neutral wire which completes the circuit, and the ground wire which provides a path for electricity to travel to the ground in case of a fault.

Understanding Electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed cable (NM), armored cable (AC), and conduit. Each kind has its own advantages and disadvantages, and the choice of the wiring type is contingent upon the particular requirements of the installation.

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 and then back to the source through the neutral wire. It is essential to ensure the wiring is put in place and maintained in a correct manner, as improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Problems

Some common electrical problems at home include tripping breakers, flickering lights and disconnected outlets. These issues can be caused by a myriad of causes, including overloading circuits, loose connections, and faulty wiring.

If you’re experiencing one of these problems, it is essential to determine the root cause and take action to fix the problem. In some cases, this may involve contacting an authorized electrician to examine and fix the wiring.
