Electricity is a vital part of our everyday lives, powering everything from the lighting in your homes, to devices we use every day.  But electricity systems are a bit complicated knowing how they function can be challenging. In this article, we’ll break down the components in an electrical circuit and show how circuits operate to power devices and appliances.

Components of an Electrical System

An electrical system has several important components that work to provide power throughout homes. This includes:

Breaker box: the central distribution point for electric power in a home that is where electricity is split into various circuits

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

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

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

Electrical Circuits

The term "electrical circuit" refers to one which allows electricity to flow from the main source (the breaker box) to the appliances and devices in a home. There are two types of electrical circuits in homes which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for most household devices and appliances, while 240-volt circuits are used for larger appliances like air conditioners and electric dryers.

Electrical circuits work 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 that is the conduit for electricity along with a neutral wire that completes the circuit, and a ground wire that provides an avenue for electricity to reach the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cables (NM), armored cable (AC) and conduit. Each comes with its own pros and drawbacks, and the choice of wiring type depends on the specific requirements that the location requires.

Electricity travels through wiring through a flow of electrons through the wire. The electrons flow from the source to the appliance or device, and back to the source via the neutral wire. It is essential to ensure the wiring is installed and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Issues

Common electrical issues in homes include tripping breakers, flickering lights, and disconnected outlets. These problems can be caused by a variety of factors that include overloading circuits, loose connections, and faulty wiring.

If you experience one of these problems, it’s crucial to pinpoint the source and take actions to rectify the issue. In some instances this could mean contacting a licensed electrician to examine and fix the wiring.
