What electronic devices contain transistors?
Practically everything. Even devices using electron tubes (e.g. microwave cookers, high power radio and TV transmitters) now generally use transistors to control the tubes.
Are vacuum tubes used in technology today?
Yes! Radar and lasers, not to mention some forms of Strobe Lights use specialized variants of Vacuum tubes, as do older Television sets still quite active. Tubes are preferred by many old Hams for nostalgic and historical value and they had and continue to have a variety of industrial applications One man's obsolescene is another's practical value, It's like typewriters or manual 35 Cameras. Tubes had a huge variety of applications including of all things compositor machines, Volt-ohmeters by RCA confirmed by 1959 Manual, and possibly the older forms of Rotary-dial phones and of course radios, television sets, tape recorders, code oscillators... They have a past-and a future but mainly the (Living history) angle though quite practical. The Russians still use them for Radio communications and Sonar systems.Vacuum tubes (especially triodes, tetrodes, and pentodes) are still the most popular form of amplification in guitar amplifiers, because of their unique tonal characteristics, and the distortion they produce when pushed past their limits.Vacuum tubes have a lifespan, so they are needed to fix tube amps.Every microwave cooker contains one vacuum tube called a cavity magnetron that generates the microwaves to cook your food. These tubes are the least expensive power microwave oscillators there are, thus their use for cooking.
What are the Advantages microwave communication?
1. Provides a high data rate. 2. cost of purchsing towers for transmission is pretty low. 3. small antennas are required. 4. No cables needed 5. Multiple channels available 6. Wide bandwidth
What is the difference between chemical earthing and conventional earthing?
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
Can 700 watt microwave compatible for 60 amp service?
As long as the voltages match a 60 amp service will handle a 700 watt microwave. The microwave will only draw A = W/V, A = 700/120 = 5.8 amps.
How do you overcome the limitations of conventional tubes at microwave frequency?
One way to overcome the limitations of conventional tubes at microwave frequencies is to use advanced technologies such as traveling-wave tubes (TWTs) or klystrons, which are specifically designed for high-frequency applications. These devices are capable of achieving higher power outputs and greater bandwidths compared to traditional tubes. Additionally, employing efficient cooling systems and advanced fabrication techniques can also help improve the performance of tubes at microwave frequencies.
What is the limitation of conventional manufacturing process?
fgfgs
What has the author A S Gilmour written?
A. S. Gilmour has written: 'Principles of traveling wave tubes' -- subject(s): Traveling-wave tubes 'Microwave tubes' -- subject(s): Microwave tubes
Which uses less energy conventional ovens or microwave ovens?
Microwave Ovens
What are the microwave tubes is based on the principal of velocity modulation?
The klystron and the traveling wave tube (TWT) are two types of microwave tubes based on the principle of velocity modulation. In these tubes, the electron beam's velocity is modulated by an external signal, leading to the amplification of microwave signals. These tubes are commonly used in radar systems, satellite communications, and other high-power microwave applications.
What is the main limitation of solid state microwave device?
The main limitation of a sold state microwave device is its surroundings. The microwave tower needs to be tall enough to overcome trees and other objects getting in the way of transmission.
What are the limitation of conventional approch of managing data explain?

Why does a microwave use less energy than a conventional oven?
Microwave takes less time to cook
How does energy efficiency of conventional oven compare to microwave oven?
Microwave ovens are typically more energy efficient than conventional ovens because they cook food faster and use less electricity. Conventional ovens take longer to heat up and cook food, resulting in higher energy consumption. Using a microwave oven for smaller meals or quick reheating can help save energy compared to using a conventional oven.
What is microwave tube?
microwave tubes are sometime called as vaccum eletrpn device... that are used to generate or amplify microwave radio frequencies.
In what products do microwave tubes find application?
Microwave tubes were primarily used in high and ultrahigh frequency applications such as radars, telecommunications equipment, military communication and control systems
What is inversion microwave cooking?
Inverter microwaves (used in inversion microwave cooking) involve a newer technology than conventional microwaves, and produce more even cooking and defrosting. They replace the capacitors and transformers of conventional microwaves with circuit boards, so they are also much lighter and can contain more cooking space than conventional microwave ovens.
