Electricity is an essential component of our life, powering everything from the lights of our homes to the appliances we use every day.  However, electric systems may be complex and understanding how they function can be challenging. In this article we’ll breakdown the various 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

An electrical system is comprised of several key components that work together to supply power to the home. This includes:

Breaker box is the central distribution point for electric power in a home, where the electricity is divided into several circuits

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

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

Electrical appliances and devices: the appliances and gadgets that rely on electricity to function.

Electrical Circuits

An electrical circuit is a pathway that lets electricity flow from the source (the the breaker box) to the devices and appliances in the home. There are two types of electrical circuits that can be found in homes that are 120-volt and circuits that are 240-volts. 120-volt circuits are utilized for the majority of household appliances and appliances, whereas the 240-volt circuits are utilized for larger appliances such as dryers, air conditioners and electric ones.

Electrical circuits work by completing the loop which allows electricity to be transferred from the source to the appliance or device. The loop is comprised of a hot wire which carries the electricity along with a neutral wire that completes the circuit as well as the ground wire which provides the pathway for electricity to reach the ground in case of a fault.

Understanding Electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each kind has its advantages and drawbacks and the selection of the type of wiring is based on the specific needs of the installation.

Electricity travels through wiring by creating a flow of electrons in the wire. The electrons flow through the wire from source, to appliance or device, and back to the source through the neutral wire. It is essential to ensure the wiring is put in place and maintained properly, since improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Problems

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

If you are experiencing any of these issues it’s essential to identify the cause and take appropriate actions to rectify the issue. In some cases, this may involve contacting an accredited electrician to inspect and repair the wiring.
