Traveling Wave Tube (TWT) - Amplification process

[@SatishKumar-jp2hs]

Tomorrow I have MWE exam sir ur videos very useful to me to prepare better thank you sir

[@yeswantyadav3277]

Tq so much sir... Maku ma sem ki topics very important tq for the work

[@MrPprasanna]

Thank you very much yeswanth

[@kurugode]

looks like all the students are uber eager to agree and praise Dr Krishna.. Are they worried about their scores ?

[@LSP1118]

TQ lot sir tommorow I have semister exam it helps me lot

[@MrPprasanna]

Thank you very much

Sir I have a doubt , what are modes of operation of helix travelling wave tube?

[@mannambhavani4266]

Nice one sir thank you😁😁

[@edimellarajasekhar1900]

Tnq sir,great explanation 👍.

[@MrPprasanna]

Thank you very much

[@achariinduja6844]

Tq soo much sir I get clarity tq sir

[@kurugode]

You have the basic structure right, but you spent more time on the drawing but not talked about WHY THE RF GETS AMPLIFIED as it travels along the length of TWT.. what does the "Interaction" of RF with Electron beam do to make the RF stronger ? How does the energy transfer from electron beam to the Helix resulting in RF amplification ? In real life, the Anode is tied to Collector (earth). Why is that ? it will help in breaking down the mechanism into smaller mechanisms than just drawing the Helix over and over.. hope you like my constructive feedback, Thank you

[@kartikeyavashisth9641]

Same feedback 👌

[@enchantedthunder5017]

i can answer your question. The electron beam shoots the electrons through the helix. There are already electrons on RF frequency running through this helix component and to output. The incoming beamed electrons, combine in synchronicity or wavelength, to basically merge. This action combines with the electron frequency of the helix part, and the signal merges, and is amplified, because there are much more electrons now, boosting the signal.

I wish you were my teacher ❤️

poor explanation! you dont understand it urself clearly!

[@somtixtreme]

Then probably you should understand it urself and make a video over it.. for the benefit of students like you looking for the relevant matter on you tube... crux of the matter... appreciate his video and ask if u still have doubts...

[@arkadebmukherjee4021]

@@somtixtreme yeah i have plans to do so once i get to understand things clearly. In words of Sir Albert Einstein one can explain a topic in simple means once he has himself understood it simply. I felt this video lacks that simplicity. Its was all frustation. I didn't mean to be disrespectful. I apologise to Sir. Thank you for rectifying me @Sourabh Singh

[@somtixtreme]

@@arkadebmukherjee4021 thank you arkadeb. I appreciate your way of looking at things.. like you I am also a wanderer looking for the right explanation.. do let me know if u get this topic right.. again kudos to you for understanding what was wrong.. and your endeavour to make it right in future..

[@makkapatisairam137]

Good explanation Sir
