A electric capacitor is a device that stores energy in an electric field across two conducting plates, separated by an insulating material. Capacitors are used in many different pieces of technology. When it comes to electric capacitors, there are a few different types that you need to be aware of. Below, we will discuss each type and what it is used for.
Electrolytic capacitors:
These are the most common type of capacitor, and they are used in a variety of applications. Electrolytic capacitors are made from a material called an electrolyte, and they have a capacitance value that is determined by the amount of voltage applied to them. They are also commonly used in analog circuits because of their low startup current and stable operation.
Polymer film capacitors:
Polymer film capacitors are similar to electrolytic capacitors, but they use a polymer film as their dielectric medium. This makes them lighter and more durable than electrolytics, and they are commonly used in digital circuits. Polymer film capacitors have higher startup currents than electrolytics, so they are better suited for high-current applications.
Electric double-layer capacitors:
Electric double-layer capacitors are similar to polymer film capacitors, but they use two different types of dielectrics.
