Electricity is an essential component of our daily lives, supplying everything from the lights of our houses to devices we use on a daily basis.  However, electricity systems are a bit complicated, and understanding how they operate can be difficult. In this article we’ll go over the elements in an electrical circuit 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 has several essential components that work to deliver power throughout the home. These include:

Breaker box: the main source of electrical power in a home, where the electricity is divided into different circuits

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

Wiring: the electrical wires that transmit electricity from the breaker box, to the outlets and switches

Electric appliances, devices and equipment: appliances and devices that require electricity for their functions.

Electrical Circuits

A circuit of electricity is a pathway that allows electricity to flow from the source (the breakers box) to the appliances and devices in the home. There are two types of electrical circuits found in homes which are 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 utilized for larger appliances such as air conditioners and electric dryers.

Electrical circuits work by creating an electrical loop that allows power to flow from the source into the device or appliance. The loop consists of a hot wire that is the conduit for electricity along with a neutral wire that completes the circuit as well as the ground wire which provides the pathway for electricity to travel to the ground in the event there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each kind comes with its own pros and drawbacks and the selection of the wiring type is contingent upon the particular requirements for the particular installation.

Wiring conducts electricity by creating a flow of electrons in the wire. The electrons flow between the origin and the device or appliance returning to the source using the neutral wire. It is crucial to make sure that the wiring is installed and maintained in a correct manner, as improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Issues

Common electrical issues that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. These issues can be caused by a variety of factors such as overloading circuits poor connections, or faulty wiring.

If you experience any of these issues it’s essential to identify the source and take action to fix the problem. In certain instances it may be necessary to contact a licensed electrician to inspect and repair the wiring.
