Is it you know what capacitor, if not then this article of today is going to be quiet interesting for you. If you have never seen a capacitor, then go outside your house and you will definitely see the capacitor in the sky. You must be wondering what I am talking crazy, but I am not doing this at all because the thing I am talking about is nothing but clouds are also a type of capacitor. If you want to know, then you will have to read this full article.
Capacitors are energy sitting devices that are widely used in television, radios, and other types of electronic equipment. Whether it is to tune Your radio in a strain, or to flash a photo from a digital camera, or to flick the channels in your HDTV, in all these places we make good use of capacitors. As I have said earlier, clouds also work exactly like the capacitors used in electronics circuits, the only difference is that they are very large compared to the electronic capacitors. Let’s get all the information related to capacitors in this article further. So without delay, let’s start with what is the capacitor.
What is a capacitor?
Capacitors are passive electrical components that stator, Store electric energy. They were formerly known as condenser. A capacitor is made up of electrical conductors and separated by an insulator. This insulating layer is called a dielectric. Although all capacitors have the same basic principle components, but the choice and configuration of the material are different from each other. These are very common elements of any electrical or electronics circuits. For example, they are used only to allow AC current only and to block DC current whereas in some places as smooth power supply output is used.
How capacitor works?
A capacitor is enabled to store energy in an electrostatic field which is generated by creating across a potential difference of conductors. So when the across voltage of a conductor is given, then a positive charge is collected in one plate of the capacitor while the other is a negative charge. That’s why physicists believe that a capacitor works electrostatically in an electric field by storing energy.
Types of capacitors
Although there are many types of capacitors I have provided information about some important capacitors below.
This type of capacitor is used in many applications whether it is audio or RF. Their values range from picofarads to 0.1 microfarads. These ceramic capacitors are mostly used in general because they are cheap and reliable, along with their loss factor is very low.
These types of capacitors are often polarized. They can offer very high capacitance values, typically above 1micro Faraday, and are often used more in low-frequency applications such as power supplies decoupling and audio coupling applications as they have frequency limits if they are around 100 if kHz.
like electrolytic capacitors, tantalum capacitors are polarized and provide very high and high capacitance levels in their volume. But this type of capacitor is absolutely intolerant to reverse biased, and often explode when it is kept under stress.
Polystyrene film capacitor
These capacitors are a very cheap form of capacitors but offer close tolerance capacitors when they are needed. They are of tubular shape where the dielectric is sandwich rolled between the two plates, but this gives them the ability to limit the frequency response of inductance to a few hundred kHz.

Polyester film capacitor
Polyester film capacitors are used where cost is given much attention because they do not offer very high tolerance. Many polyester film capacitors have a tolerance value of 5 percent or 10 percent which is very adequate for most applications.
