What is meant by generation?
What is mean by thermionic generation is that electricity is created as a hot electrode will emit electrons onto a cold electrode. Elements like cesium are often used to help bridge the gap and improve the output.
What are the 3 applications of convection in relation to thermionic emissions?
Convection plays a role in thermionic emissions by enhancing heat transfer, which can improve the efficiency of thermionic devices. One application is in thermionic converters, where convection helps maintain optimal temperature gradients for electron emission. Additionally, convection can be utilized in cooling systems for thermionic emitters to prevent overheating. Lastly, convection can influence the design of thermal management systems in space applications, where thermionic devices may be used for power generation.
What has the author Shakir Mohamad Ali written?
Shakir Mohamad Ali has written: 'Frequency multiplication and harmonic generation in thermionic valves'
Where does the thermionic emission occur in cathode rays tube?
Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.
What is the uses of thermionic emission?
Thermionic emission is commonly used in devices such as vacuum tubes and cathode ray tubes to generate and control electron beams. It is also used in some types of electron microscopes, x-ray tubes, and microwave tubes. Additionally, it is utilized in some types of detectors and ionization gauges.
What are the computers that where invented in the first generation of computer?
ENIAC,EDSAC,EDVAC,UNIVAC(I &II) and MARKS1
What is meant by a second generation star?
a second generation star is a star that has died a from that become a new star
What is a thermionic thermometer?
A thermionic thermometer is a device that measures temperature by detecting the electrons emitted from a heated surface. It relies on the thermionic emission phenomenon, where electrons are released from a heated cathode and collected at an anode to generate a measurable signal related to the temperature of the cathode.
Who has invented first thermionic wave?
J.A.Fleming
What is zeroth generation?
Zeroth Generation Computers 1642-1946. Basically covers the history of early mechanical computers from Charles Babbage and software programming ideas by Ada Lovelace to the machine age of electromagnetic relays and thermionic valves where the operators had complete access to the machine and inputted the programming language by hand.
What is meant by forth generation system?

What is thermionic thermometer?
A thermionic thermometer uses the thermionic emission of electrons from a heated filament to measure temperature. When the temperature increases, the emission of electrons also increases, allowing for a correlation between temperature and electron emission. These thermometers are used in high-temperature applications and can provide fast response times.
