🔴 ANTENNA || Communication System - Part 3 || in HINDI

- Опубликовано: 18 янв 2018
- In this Physics video lecture in Hindi for class 12 we explained the working of an antenna, basically dipole antenna. We considered the experiment conducted by Hertz to prove the existence of electromagnetic waves. Accelerated charged particles can create electromagnetic waves. As in oscillator charges move back and forth, an oscillator is a source of electromagnetic wave. When two colinear rods are attached to the LC oscillator they, as whole, work as a dipole antenna. Dipole antenna is known as Hertzian antenna. Similarly there can be a monopole antenna which is known as Marconi antenna.

Bahut bhadiya sir ab samajh gye how antenna works!!!
Sir ur just awesome ..... very nice explained
Tq sir
This helped me a lot and
I am a audio engineer
Sir please I request to make a video on characteristic curve of transistor in common-emitter connection, plz sir
Very very great.. I cleared my doubt since a long time in my mind.. Keep it up... 👍🏻👍🏻👍🏻
Thanks soo much sir
Very yusful very nice video ❤
Sir make a video on Bose eiensteen , farmidirac statistics theorem
Very nyc explntn
What is the max distance. Is distance depend on voltage or not
Thanks a lot.
thnxx 😇😇
sir aapnar bideo aamay anek ....... bhalo lage. bsc part 2 ....
Nic sir...acca laga vidio..sir B.SC ki topic me kuch jada vidio milti to accha hota..thq sir
Very nice video
Thankyou Sir
Nice explanation😊👍👌👌
Sir aap bhut samchate hai thx sir ji
You are the best sir....
RITU MOHAPATRA same for Sir
Very good afternoon Sir, please make video on basic maths mainly on integration and differentiation
hubbly i want to say that make some video of bandwidth & modulation & demodulation
thanks Sir
The antenna structure is a open circuit , ryt ? How current flows there ? Only potential would be present there. Please help me understand here.
Sir, electrical signal wave me convert kse hota he?
Sir Please please reply.....
At a constant volume V1 molar specific heat capacity at a constant volume is Cv. But if we change the constant volume to V2. Is then also value of Cv is same?
OR another way to ask same question.
If one mole gas is compressed to small volume V1 and temp is 100°C then we supplied dQ heat temp increase to 101°C BUT same gas is now expanded to V2 ( V2 > V1) to temp 0°C now how much heat we have to supply to increase temp 1°C with same volume V2? Is that same dQ?
Àaa
Fabulous video sir
Please tell me where are u from in chandil I'm also from jharkhand
Helholtz equation per ek video sir. Please
Which software do you use to make video sir
Thank you
sir plzz upload video about microstrip patch antenna plzzz sir
Sir you need to make a video on FM(frequency modulation) AM(amplitude modulation) in brief
Available hai.
Tq sir
I request to edu point upload video about wave optics
Sir , I request u to upload video about wave optics
Sir i have doubt that dipole antenna is open circuited , then how electron will flows????? Please sir clear my doubts. 🤗🤗🤗🤗
It is becz of the ______________________________________________________(i will answer it when I fully understand the sub)
❤️❤️❤️❤️❤️
Plzzzz ssir 11,12 ke sareee physic k topic pddaa dijiye
Sir agr charges constant velocity s move kren gi to EM waves nh banti..... accelerated hone p hi bnti hn asa kyu????? Plz Plz plz btyn
Here, when we have LC, we get oscillation at the frequency determined by L and C components. So , we have different voltages at the point.
It is enough for board exam?
supar
Woo
NAMASKAR SIR ❤️🙏😍🙏
Sir Part 2 nahi mil raha
sir please make a video on Tesla coil
Hello RIMA KUMARI !
I shall try.
why the length of the monopole antenna should be greater than wavelength/4 ?can you share the derivation or prove of this? thanks
To facilitate highest energy reception it is important that the length of antenna is comparable to that of the wavelength of em wave .
This happens only at certain frequencies
sir same antina receiver transmtin antna ho sakta?
Antenna behaves as receiver as well as transmiter when the communication system is bidirectional. For example mobile communication
+harshit dixit sir why antina is neccesory ..y we cant directly use satellite in communication
+harshit dixit sir actully i m having pcs interview on 12th jan and i have completed engineering ...
Kindly give ideas to make video to my postgraduate students
Full lesson
nyc
Hello Mehak Arora !
Thank you very much for supporting this channel.
Aap sab ki dua se hi ye channel hai.
Kaise aadmi ho yaar open circuit mai current flow karwa diya 👌👌👌👌👌👌👌👌👌👌
Unipolar antenna dekhe hain aap ya fir aise hi mazak mazak me comment kar diye?
Polarizer ka concept pata hai?
Wahan bhi closed circuit hota hai kya molecular chain ka, jisme current flow karne se electric field cancel ho jaata hai?
Current agar hamesha closed circuit me hi flow karega, to aap kahna chahte hain ki kahin bhi kabhi bhi charge density change nahi kar sakta.
Aap jaiso par mujhe sympathy hai.
Get well soon......
God bless you.
also definition write
Sir please Puri jankaari so
Can you explain in English
LC oscillator is slightly wrong
+ajit sakri
Please send us the correct figure at arijitdaripa77@gmail.com so that we can improve.
Thanks.
Slightly nhi pura galat hai aisa lag rha h ke majak chal raha h Physics ka
कौन कौन इस विडियो को 2023
में देख रहा है।,।।
🎉🎉
Das versteht ja keine Sau...
Nhi h conceptual clarity to kyon banate ho videos physics ka majak mat banao
Aap sahi kar dein aur ek video banayein.
Main aapka abhari rahoonga.
God bless you.....
