Posted by Adelaide Electrical on 2 Feb 2026

Electricity is an essential component of our everyday life, powering everything from the lights in your homes, to appliances that we use each day.  However, electric systems may be complicated making it difficult to understand how they operate can be challenging. In this guide we’ll go over the various components in an electrical circuit, 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 important components that work to provide power throughout the home. They include:

Breaker box is the central source of electrical power in a home in which the power is split into various circuits

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

Wiring: the electrical wires that transport power from the breaker box, to the outlets and switches

Electric appliances, devices and equipment: the appliances and gadgets that rely on electricity to function.

Electrical Circuits

A circuit of electricity is a pathway which allows electricity to flow from the source (the breaker box) to the appliances and devices in the home. There are two kinds of electrical circuits that can be found in homes: 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 like air conditioners and electric dryers.

Electrical circuits work by completing an electrical loop that allows power to flow from the source into the appliance or device. The loop consists of a hot wire which carries the electricity and a neutral wire which completes the circuit and a ground wire that provides an avenue for electricity to travel to the ground in the event there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many kinds, such as non-metallic sheathed cable (NM) and armored cable (AC) and conduit. Each has its advantages and disadvantages, and the choice of wiring type depends on the particular requirements for the particular installation.

Electricity travels through wiring through a flow of electrons through the wire. The electrons travel from the source to the device or appliance, and back to the source using the neutral wire. It’s essential to ensure that the wiring is installed and maintained correctly, as defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues at home include tripping breakers, flickering lights, and disconnected outlets. The causes of these issues could be by a myriad of causes such as overloading circuits broken connections, and defective wiring.

If you experience any of these issues it’s essential to identify the source and take steps to correct the issue. In certain instances it may be necessary to contact an accredited electrician to look over and fix the wiring.

Concluding as well as a Call to Action

In conclusion, understanding how electrical wiring works is vital to ensure the safety and security of your home’s electrical system. If you follow the rules laid out in this guide, you can stay secure and avoid potential dangers.
