Introduction:
Vacuum tube is called "Vacuum Tube" in English. It is one of the oldest components used in electronics apart from electronics. It is commonly referred to as "Valve".It is a tube that is made under vacuum. It is in the form of a bulb with an electrical capacitor inside. Two different electrodes meet the two sides of the tube, which is used in the form of an amplifier.
Vacuum tubes were commonly used to amplify sound signals, such as for radio and television. In addition, it is also used in other applications such as components of computers, radars and other electronics.
Vacuum tubes types:
Vacuum tubes, also called electron tubes or valves, were an important component of early electronic devices and were used as amplifiers, oscillators, and switches in a variety of applications. Here are some common types of vacuum tubes:
Triode:
The simplest vacuum tube, consists of three elements: a cathode, an anode (plate), and a control grid. It was used as an amplifier and as a switch.Tet rode: A vacuum tube with four elements: a cathode, two grids, and an anode. It was developed to overcome some of the limitations of the triode and was used as an amplifier and oscillator.
Pentode:
A vacuum tube with five elements: a cathode, two grids, a screen grid, and an anode. It was developed to improve the performance of the tetrode and was used as an amplifier and oscillator.
Beam tetrode:
A vacuum tube with four elements that uses a beam of electrons to amplify the signal. It was used in high power audio amplifiers, television sets and other applications.
Cathode Ray Tube:
A vacuum tube that directs a beam of electrons onto a fluorescent screen to produce an image. It was used in early television sets and computer monitors.
Thyratron:
A gas-filled tube that can be used as a switch, oscillator or amplifier. It was used in early computers and other electronic devices.
Magnetron:
A vacuum tube that produces high-power microwave signals used in radar, microwave ovens, and other applications.These are just a few examples of the many different types of vacuum tubes that have been developed over the years. Although vacuum tubes have been largely replaced by solid-state electronics, they remain an important part of the history of electronics and are still used in certain applications.
Vacuum tubes vacuum tubes advantages:
Tubes, also known as thermionic amplifiers or tubes, play an important role in electronics. It is one of the oldest technologies in the world of electronics with a history of at least 100 years.
Vacuum tubes have several advantages such as:
Ability to operate at high frequencies:
Vacuum tubes operate well at high frequencies.
Accuracy:
The use of vacuum tubes proves to be better in terms of accuracy in electronic devices.
Vacuum systems:
Vacuum tubes operate on a vacuum system, which protects them from electrical noise.
High energy support:
Vacuum tubes support high energy and are capable of operating under electrical stress.
Long life:
Vacuum tubes have a long life and their usage reduces their cost of ownership.
Wide range of efficiency:
Vacuum tubes can be used for a wide range of electrical range efficiency.
Vacuum tubes vacuum tubes disadvantages:
1. Weight:
The weight of vacuum tube is very heavy due to which it cannot be easily moved.
2. Power loss:
Vacuum tubes consume a lot of power.
3. Heat build-up:
Using vacuum tubes for long periods of time leads to heat build-up.
4. More perishable:
Vacuum tubes are more perishable and have a shorter lifespan.
5. Large volume requirement:
Vacuum tubes require large volume which makes their installation difficult.
Uses of vacuum tube:
Acoustics:
Vacuum tubes amplify sound signals using electricity. They are used in radio, television, hi-fi amplifiers and other devices.
Electronics:
Vacuum tubes are also used to amplify electrical signals in electronics. They are used in amplifiers, scanners, radars and other devices.
Electronics:
Vacuum tubes are also used in the field of electronics. They are used to get long distance information.
Defense Industry:
Vacuum tubes are also used in the defense industry. They are used for radar, switching, and switches.
Products:
Vacuum tubes are used to make electrical components. They are used in flight, source, and other equipment
