What is a Capacitor?

When it comes to the electrical systems in our homes, many of us don’t think twice. But without the electrical systems, we could say goodbye to Netflix binges, fully charged smartphones, light, air conditioning and more.

Electrical systems are complex as they are composed of many different parts, all which serve different functions to generate and supply electricity. Capacitors, for example, are an essential component of your electrical system, yet many don’t know what capacitors are or why they’re important. Here, you’ll learn everything you need to know about capacitors.

Electrical System Capacitors
To explain what a capacitor is and how it functions, it’s best to have a basic understanding of current. Current basically means that negative charges are moving one way through a wire, while a positive charge is moving in the other direction. A capacitor is essentially two conducting plates that have a dielectric or an insulator between them. The dielectric has electromagnetic properties that block the flow of current, while also allowing an electric field to pass through it. As negative charges start building up on one plate, the positive charges begin moving the other way, building up on the other plate. While there won’t be any current passing through the dielectric, there will be a large difference in the charge of the plates. Ultimately, this will create an electric field in the dielectric.

Why Are Capacitors Important?
Unless you have some electrical know-how, understanding capacitors can feel overwhelming. Ultimately, capacitors serve an important function within the electrical system in your home. Capacitors are extremely important, not just in your personal electrical system, but to the rest of the world. For starters, capacitors are one of four primary components used in powering all electronics. They are a crucial part of every circuit because they provide and store energy.
