Electricity is an essential component of our lives, powering everything from the lights in our homes to the appliances that we use each day.  But electric systems may be complex, making it difficult to understand how they work can be difficult. In this article, we’ll break down the elements of an electrical system, and describe how circuits function to power devices and appliances.

The components of an electrical system

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

Breaker box: the main source of electrical power in homes, where the electricity is divided into several circuits

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

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

Electronic appliances and gadgets: appliances and gadgets that rely on electricity to function

Electrical Circuits

An electrical circuit is a path that allows electricity to flow from the main source (the the breaker box) to appliances and devices within the home. There are two kinds of electrical circuits in a home: 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 dryers and air conditioners.

Electrical circuits work by creating an electrical loop that allows power to be transferred from the source to the device or appliance. The loop consists of a hot wire that transports the power and a neutral wire which completes the circuit and the ground wire which provides a path for electricity to reach the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each type has its own advantages and disadvantages and the selection of the type of wiring is based on the specific needs that the location requires.

Wiring conducts electricity through a flow of electrons that travel through the wire. The electrons travel through the wire from source, to appliance or device returning to the source via the neutral wire. It’s essential to ensure that the wiring is installed and maintained in a correct manner, as defective wiring could lead to electrical dangers like shocks and fires.
