Do you know that this What is capacitor in HindiCapacitors (also known as condensers), these are energy-storing devices which are specially used in televisions, radios, and other types of electronic equipments.
Whether it is to tune your radio in a station, or to flush from a digital camera for a photo, or flick the channels in your HDTV, in all these places we use Capacitors well.
As I have already said that clouds (clouds) also work like capacitors used in fine electronic circuit, the only difference is that they are very large compared to Electronic Capacitor. Let us further get all the information related to Capacitors in this article. So let's start without delay, what is the capacitor.
What is capacitor – What is Capacitor in Hindi
Capacitors are Passive Electrical Components that store Electric Energy. He was earlier known as Condenser. A capacitor is made of electrical conductors and is separated by an insulator.
To this insulating layer dielectric It is said. Although all capacitors use the same basic princess components, but the choice and configuration of the material is 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 and Dc current To block To do, in some places a smooth power is used for Supply Output.
Capacitor function
A capacitor is enabled to store the energy in an electrostatic field which is generated by the across the across the across potential differential So when a conductor's across voltage is given.
Then a positive charge is collected in a plate of capacitor, while in the other, Negative Charge. Therefore, physicists believe that a capacitor works by storing the energy and electrostatically in an Electric Field.
Electric Charge And Potential differentice Ratio of (voltage) is called capacitance. It is measured in Farads (Unit). This is the most main parameter to describe a capacitor.
Capacitance is the highest when the distance between the conductors is the lowest and the surface of the conductors is the highest. Ideal capacitors There are only in theory which are fully described by capacitance, but exist some Limitations in Real World.
For example Conductor and lead wires produce parasitic inductance and resistance. At the same time, the Static Electric Field has its own maximum strength limit, which is described from Breakdown Voltage, as well as the current leak which is from the dielectric is called leakage current.
Type of capacitor
Although there are many types of capacitors, but I have provided information about some important Capacitors below:
Ceramic Capacitor
This type of capacitor is used in many applications whether it is audio or rf. Their values ranges from picofarads to 0.1 microfarads. These Ceramic Capacitor is mostly used from common to because they are cheap and reliable, along with their loss factor is very low.
Electrolytic capacitor
Capacitors of this type are often polarized. They can offer very high capacitance values - typically Above 1μf, and they are often used more in low frequency applications – such as Power Supplies, Decoupling and Audio COPLING applications, what are their frequency Limit is if it is Around 100 KHz.
Tantalum capacitor
Like electrolytic capacitors, tantalum capacitors are also polarised and provide too much and high capacitance level in their volume. But these types of capacitors are absolutely intolerant towards Reverse Biased, and often explode when they are kept under stress.
Also, they should not be used in high ripple currents and voltages. Both of them are leaded and surface mount formats available.
Silver mica capacitor
Silver Mica Capacitors are no longer used, but it provides too much high level stability, low loss and accuracy where space is not a matter of any issue. They are used in primarily RF applications and their maximum values are limited to 1000 PF only.
Polystyrene film capacitor
Polystyrene capacitors are very cheap form of capacitor but close tolerance capacitor offers when they are required. These are of tubular shape where Dielectric is rolled Sandwich between the two plates.
But this gives them the ability to limit the frequency response of inductance to FEW HUNDRED KHz. These are only available from the Leaded Electronics Components.
Polyester film capacitor
Polyster film capacitors are used there where the cost is very focused because they do not offer too much high tolerance.
The tolerance value of many polyester film capacitors is 5% or 10%, which is very adequate for most applications. These are only available from the Leaded Electronics Components.
Glass capacitors
As the name suggests that in this capacitor, glass is used from the dielectric. Although it is very expensive, but still these capacitors offer the performance of very high levels in terms of extramely low loss.
High RF Current Capability, No Piezo-Electric Noise and other features make them ideal for many performance RF applications.
Supercap
It is also called Supercapacitor or Ultracapacitor, as it is a very large capacitance value of capacitors, which can be close to Several Thousand Farads. They are mostly used in Memory Hold-up Supply and Automotive Applications.
What is capacitance and how to increase it
How much a capacitor can store the electrical energy of how much Amount is called Capacitance. Capacitor's capacitance is like a water bucket, that means the larger the bucket can remain in it, the more the Capacitor can remain in it.
Capacitor's capacitance is mainly three measures to increase the capacitance
Surface area – Surface Area is written to A, it means that two conductive plates that make Capacitor, the bigger the area will be as much as it will be.
Distance – Distance is written as D, it means that the small distance between two conductive plates will be as big as the big capital.
Dielectric Material – The material between these two plates, which sees both plates, which is also called Dielectric, then the more permittivity of this dielectric will be as much as it will be as much as its capacitance.
How is Capacitance Measure?
Capacitor's size is measured units called Farads (F) in which English Electrical Pioneer Michael Faraday (1791–1867) is named above.
One Farad is a very amount capacitance, so most of the capacitors used only a few fractions of a Farad typically Microfarads (Millionths of a Farad, written μF), Nanofarads nf), and picofarads (Million-Millionths of a Farad, Written PF).
Standard Units of Capacitance
- Microfarad (μF) 1μF = 1/1,000,000 = 0.000001 = 10-6 f
- Nanofarad (nf) 1nf = 1/1,000,000 = 0.000000001 = 10-9 f
- Picofarad (pf) 1pf = 1/1,000,000,000,000 = 0.000000000001 = 10-12 f
What is the work of capacitor?
Do you know what is less of the capsiter? We can use capacitors in many tasks. Let's get some information about them.
1. Capacitors are used to store the charge, so it is used in the camera with a flash. Together big lasars also use this technique very bright and instantaneous flashes.
2. Capacitors are used to remove ripples. If a line in which DC Voltage is going and contains ripples or spikes in it, then these peaks can be easily removed by using a big capacitor.
3. Capacitor can block DC Voltage. So if you put a small capacitor in a battery, then there will be no current flow in it, once it is charged between the two poles of the battery.
What is the main function of Capacitor?
Capacitor's main task is to store electricity and release it in circuit again.
Are Capacitor Dc or AC?
Capacitor is both DC and AC. Capacitor is charged during DC Circuit and discharge during AC Circuit.
