Posted by Local Electrician Western Sydney on 17 Jun 2025

Electricity is an integral part of our daily life, powering everything from the lighting in our homes to the gadgets that we use each day.  But electricity systems are complex knowing how they function can be challenging. In this article we’ll breakdown the components 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 key components that work together to supply power to homes. These include:

Breaker box: the central source of electrical power in homes in which the power is divided into different circuits

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

Wiring: the wires that transmit electric current from the box, to the outlets and switches

Electric appliances, devices and equipment: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

An electrical circuit is one that lets electricity flow from the main source (the the breaker box) to appliances and devices within the home. There are two types of electrical circuits in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for the majority of household appliances and appliances, whereas 240-volt circuits are used for larger appliances like air conditioners and electric dryers.

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

Understanding Electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed cables (NM), armored cable (AC) and conduit. Each has its own advantages and drawbacks, and the choice of wiring type depends on the specific requirements of the installation.

Electricity travels through wiring through a flow of electrons that travel through the wire. The electrons travel from the source to the appliance or device returning to the source through 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.

Common Electrical Problems

Some common electrical problems in homes include tripping light bulbs, flickering breakers and disconnected outlets. These problems can be caused by a variety of factors that include overloading circuits, loose connections, and faulty wiring.

If you experience any of these issues, it’s crucial to pinpoint the source and take steps to correct the issue. In some cases it may be necessary to contact a licensed electrician to inspect and repair the wiring.

Conclusion as well as a Call to Action

In the end, knowing the way electrical wiring functions is crucial for ensuring the safety and reliability of the electrical system in your home. By adhering to the guidelines laid out in this document, you can stay safe and prevent potential hazards.
