What is a Capacitor?

Before we dive into the importance of capacitors in air conditioners, let’s first understand what a capacitor actually is. In simple terms, a capacitor is an electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material known as a dielectric.

Capacitors come in various shapes and sizes, but they all serve the same fundamental purpose – to store and discharge electrical energy. When an air conditioner is turned on, the capacitor stores a charge in the form of voltage. This stored energy is later released to start the compressor and fan motors, enabling your air conditioner to function properly.

Capacitors act as a type of “battery” for your air conditioner, providing the initial jolt of power needed to start the motor rotation. Without a functioning capacitor, your air conditioner will struggle to start up and may even fail to operate.

It’s important to note that there are two main types of capacitors used in air conditioners: the start capacitor and the run capacitor.

The start capacitor is responsible for providing the initial voltage jolt to start the motor rotation. Once the motor starts running, the run capacitor takes over and provides a continuous stream of energy to keep the motor running smoothly.

Now that we have a basic understanding of what a capacitor is, let’s explore why capacitors are crucial components in the operation of air conditioners.
