Electricity is a vital part of our daily lives, supplying everything from the lights of our houses to devices that we use each day.  But electricity systems are a bit complicated and understanding how they function can be challenging. In this article we’ll breakdown the 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.

Components of an Electrical System

A home’s electrical system includes a number of key components that work together to provide power throughout homes. This includes:

Breaker box: the central distribution point for electric power in a home in which the power is divided into several circuits

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

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

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

Electrical Circuits

An electrical circuit is one that lets electricity flow from the main source (the the breaker box) to the devices and appliances in a home. There are two types of electrical circuits found in homes that are 120-volt and 240-volt circuits. 120-volt circuits are utilized to power most household appliances and appliances, while 240-volt circuits are used 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 to the device or appliance. The loop consists of a hot wire which is the conduit for electricity along with a neutral wire that completes the circuit, and a ground wire that provides the pathway for the electricity to get to the ground in case the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cables (NM) and armored cable (AC) and conduit. Each has its own advantages and drawbacks, and the choice of wiring type depends on the specific needs for the particular installation.

The electricity travels through wires through the creation of electrons through the wire. Electrons move between the origin and the appliance or device returning to the source using the neutral wire. It is essential to ensure the wiring is installed and maintained correctly, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Problems

Some common electrical problems that homeowners face include tripping the breakers, flickering lights, and electrical outlets that are not working. These problems can be caused by a myriad of causes such as overloading circuits broken connections, and defective wiring.

If you’re experiencing one of these problems, it is essential to determine the source and take steps to correct the issue. In some cases it may be necessary to contact an authorized electrician to look over and fix the wiring.
