Posted by Local Electrician Doncaster on 15 Jan 2026

Electricity is a vital part of our everyday lives, supplying everything from the lighting in our houses to devices we use on a daily basis.  But electrical systems can be a bit complicated and understanding how they function can be challenging. In this article we’ll go over the components of an electrical system and show how circuits operate to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

An electrical system is comprised of several essential components that work to deliver power throughout homes. This includes:

Breaker box: the central distribution point for electrical energy in a house in which the power is divided into different circuits

Outlets and switches: the places where electricity is delivered to devices and appliances

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

Electronic appliances and gadgets: the appliances and devices that require electricity for their functions.

Electrical Circuits

An electrical circuit is a pathway that lets electricity flow from the main source (the breakers box) to appliances and devices within a home. There are two types of electrical circuits found in a home which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are utilized for most household devices and appliances, while 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 to the device or appliance. The loop is comprised of a hot wire which carries the electricity, a neutral wire that completes the circuit as well as the ground wire which provides a path for electricity to reach the ground in case there is a problem.

Understanding the electrical Wiring

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

Wiring conducts electricity through the creation of electrons in the wire. Electrons move through the wire from source, to device or appliance and then back to the source using the neutral wire. It’s essential to ensure that the wiring is installed and maintained in a correct manner, as defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues at home include tripping breakers, flickering lights and electrical outlets that are not working. The causes of these issues could be by a variety of factors such as overloading circuits poor connections, or faulty wiring.

If you experience one of these problems, it is essential to determine the source and take steps to correct the issue. In certain instances it may be necessary to contact an accredited electrician to inspect and repair the wiring.
