Posted by Local Electrician Glenfield on 9 Jun 2025

Electricity is an essential component of our daily life, powering everything from the lights of our homes to the gadgets we use on a daily basis.  But electricity systems are a bit complicated, and understanding how they work isn’t easy. In this article we’ll go over the components that make up an electric system, 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

An electrical system is comprised of several important components that work to supply power to homes. They include:

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

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

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

Electrical appliances and devices: devices and appliances that use electricity to function.

Electrical Circuits

A circuit of electricity is one which allows electricity to flow from the source (the breakers box) to the devices and appliances in a home. There are two kinds of electrical circuits found in a home: 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are employed for the majority of household appliances and appliances, whereas the 240-volt circuits are designed for larger appliances such as dryers and air conditioners.

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

Understanding the electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed wire (NM), armored cable (AC) and conduit. Each type has its advantages and disadvantages and the selection of wiring type depends on the particular requirements that the location requires.

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

Common Electrical Issues

The most frequent electrical problems found that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. The causes of these issues could be due to a variety of reasons such as overloading circuits loose connections, and faulty wiring.

If you are experiencing any of these issues it’s crucial to pinpoint the cause and take appropriate steps to correct the issue. In certain instances it may be necessary to contact an authorized electrician to inspect and repair the wiring.

Final Conclusion, as well as a Call to Action
