Posted by Emergency Electricians Adelaide on 7 Apr 2026

Electricity is an essential component of our lives, supplying everything from the lights in our homes to the devices we use every day.  But electrical systems can be a bit complicated, making it difficult to understand how they function isn’t easy. In this guide, we’ll break down 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.

The 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: the main source of electrical power in a home, where the electricity is split into various circuits

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

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

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

Electrical Circuits

The term "electrical circuit" refers to one that allows electricity to flow from the source (the breaker box) to the appliances and devices in the home. There are two types of electrical circuits that can be found in the home that are 120-volt and circuits with 240-volt voltage. 120-volt circuits are employed for most household devices and appliances, while 240-volt circuits are used for larger appliances such as air conditioners and electric dryers.

Electrical circuits function by creating an electrical loop that allows power to be transferred from the source to the device or appliance. The loop consists of a hot wire that carries the electricity, a neutral wire that completes the circuit, and the ground wire which provides an avenue for the electricity to get to the ground in case of a fault.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cable (NM) as well as armored cables (AC), and conduit. Each type has its advantages and disadvantages, and the choice of the wiring type is contingent upon the specific needs of the installation.

The electricity travels through wires through the creation of electrons in the wire. Electrons move through the wire from source, to device or appliance, and back to the source through the neutral wire. It is crucial to make sure that the wiring is installed and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Problems

The most frequent electrical problems found that homeowners face include tripping the breakers, flickering lights, and disconnected outlets. These issues can be caused by a myriad of causes that include overloading circuits, poor connections, or faulty wiring.

If you’re experiencing any of these issues it’s essential to identify the cause and take appropriate steps to correct the issue. In certain instances, this may involve contacting a licensed electrician to look over and fix the wiring.
