Why Electric Discharge happens from Pointy Region (in Hindi)
HTML-код
- Опубликовано: 19 сен 2024
- In this Physics video in Hindi for Class 12 we explained why electric discharge from a high voltage object happens from its pointy region. This is the effect of high electric field generated at the surface of a pointy (sharp edge) region, despite the whole surface is at the same potential.
Electric field at a charged surface is proportional to the surface charge density there. And the surface charge density is inversely proportional to the radius of curvature of the region. Hence the less is the radius of curvature of region at a surface, the more is the intensity of electric field.
Thank you so much sir for this phenomenal lecture.
This phenomenon is called corona and it can also be visible in bluish colour in the high voltage overhead transmission line. To overcome this effect we have to use a circular conductor instead of a triangular or any other shape.

Hello sir this video is soo informative.....
Thank you so much guru dev 🙂🙂
Hello Bhargav,
You are welcome. 👍👍
really needed topic sir. you are coming with very interesting topics.... GREAT SIR!
SIR! I AM BIG FAN OF YOU... You explain concept very well
We are capble😗 to understand 🧐 the science 🤓 topic easily😋 because of you😄.......................................................😄
Thanks sir.....🤗
Hey Anuj,
🙏🙏
Sir thanks sir i have studied this phenomenon as corona discharge but i was unable to understand this . But after watching your lecture its crystal clear
You are Richard Fenyman of 21st Centuary! From where you have learnt all these things? Are these answers of "WHY" questions taught in B.Sc or you have found on your own by reading books? What is the seceret behind you knowing/understanding all these things?
Please reply sir please as we also want to understand science like you...
Love You Sir...
Lots of Respect from Gujarat...
Hey Kavan,
Gyaan to har jagah bah raha hai.
Bas samet lo... 👍👍
Sir... Why does electricity go at almost the speed of electromagnetic waves....?? Please explain ...? and how does it happen ....??
Clear explanation sir
Hey Harish,
It seems clear to you, because your concept is clear. 👍👍
@@edupoint.physics thank you sir, ek request thi , electric shock kese lagta hai. Static electric shock and dynamic electric shock kese lagta hai . Doubt tha sir
Sir pls make a video on beta decay in simple terms 🙏🏻
Hello sir ,,helpful information aur
Sir khule maidan me bijli girna ka concept kya hai sir please make video .🙏🏻🙏🏻🙏🏻
Bijli ka kya hai... Itna high voltage hai kuchh bhi ho sakta hai.
@@edupoint.physics but sir khule maidan me bijli girne ka chance jyada kyu hota hai
Respected sir this video will very helpful for me whenever I make a Tesla circuit I can't understand what happens ...But now it's clear.
Sir please help me. When we say we bring a charge from infinity to a point near another charge, why do we say that the work done in that case is QV and not infinite. Sir as per the definition of work, it should be FS and as the charge has been displaced infinitely, the work done should be infinite.
And for the part of this video it was very informative sir. Thank you for helping us grow our knowledge. 🙏🙏
Hello Shivam,
Please watch proper video.
Are bhai apka concept galat hai
Force change hota hai infinity se ek point tak Late Waqt aur distance bhi
Yahi se concept of potential develop hota hai
Integrate kro pta chl jaega👍
Thanks sir....good explanation.
Thanks a lot sir....SIR EK VIDEO MEI JRUR AAPKA INTRO DIJIEGA
Sir kya hum isse lighting kra sakte h???
Kya baat kya baat kya baat owt of the world
I can got a new fundamental concept, Thank you sir.
Hello sir🙏🙏,
Sir, jab kise halke toote wire pe electric current hai, toh us toote wire par jab pani girega or voh pani jab niche girega toh us mai electric current hoga???? Sirrr..
Sir, please response.🙏🙏
Thank you sirji🔥🔥❤️❤️
Keep it up sir. You always bring interesting topic.
Sir in case of conductor the charge spread on whole surface but in case of insulator the charge spread in whole volume. Sir please make a vedio for that topic. Please sir🙏🙏🙏🙏🙏
Good afternoon sir 🙂
Good afternoon, Rituparna.
Another great video..
The video raised more doubts then clearing past one..
And I'm very curious to either solve them or see you making videos on them too..
Milte hai yahi par..😊
Thank you sir.. ❤️❤️
Hello Dhruv,
"... raised more doubts that clearing past one.."
Do you wanna say, I should retire from teaching?
😄😄😄
@@edupoint.physics No sir.. I meant that now I've more questions to find answers as this video has boosted some points which were unknown for me.. Now I've gained some more knowledge in this video and hence can work on more doubts..
More knowledge means more new doubts to tackle this is all what i wanted to say.. And this knowledge ofcourse gonna help me in my journey.. or we all know you're already with us in our journey..
Rip my english.. 😂😂
Edit: A teacher can't retire even if he/she wanted to do so as long as he/she is always surrounded with the students..😂😂..
Keep making videos..
sir at 3:00 is it radius of curvature or radius of the concern sphere?
NYC topic sir
Hello Harshit,
Thank you. 🙏
🙏🙏😇
Sir, please make a video on how does moving charge generates magnetic field
Sir i have a question that at the time of discharging why we see blue coloured light please answer sir?????????
E = hv
Sir mujhe pata h ki aapke paas time ni rhta......
Hum logo ke nhi to future me hamare juniors ke chemistry ke doubts bhi ese hi kr dijiyega....
Chemistry me to boht hi saare doubts hn
🤗🤗thnx sir
Hello Aishwarya,
Oh dear! Chemistry is not my subject. It is dreadfully difficult for me.
Fir bhi kabhi kabhi koshish karta hoon.... Par logo ko chahiye hi nahi hota. 1 din me 20 log bhi pura nahi dekhte hai video ko. Achchha nahi hoon na chemistry me....
@@edupoint.physics Sir, Me bhi physics me acchi ni thi, but aapke karan......
Nice video
Hello Sumit,
🙏🙏
Sir , tensile Stress me keya volume change hoga ???
Hello sir,
Can intensity of ray of light increases when we incident a ray of light on a mirror at 0° from normal??
Yes.
More is the angle with normal, more is the spread of light on the surface.
Gjb sir G.
Sir kya electric discharge (flow of electricity) is possible through air molecules????
Yes, I got it.
🙏🙏🙏
Thank u sir.
Sir mera question h ki hmm aasmaan se jo bijli girti h usse store kyo nhi krte agr hmm usse store kr lenge to bhut saara paisa bachega time bachega aur wo to bhut high intensity ka hota h agr hmm ek bhi bijle ko store kr le to bhut sahar ki bijli bch skti h
Im big fan you Sir! Even I'm pursuing BSc chemistry from allahabd university I don't know why I love to learn from you ! and I'm with you since my class 12th. I love to do experiments particularly on chemistry AND on Rocket Science on my channel SERIES EXPERIMENTS and I love you sir thank you for teaching us!
Hello Ratnesh,
Thank you very much for your support. 🙏🙏
And... Best of luck for your channel. 👍👍
Very informative and interesting 🥰...
Thank you sir
Is this is potential energy of a charge

The correct way to celebrate this independence day is to start developing independent thinking. Making students and their minds independent and not a slave of system.
That is the way we can make students love India not foreign
Sir, why there is more magnetic field at the poles of bar magnet and why at the middle of Bar magnet there is less magnetic field?
Please reply and answer me sir..
Hey Alok,
You can watch videos on magnetism.
New videos will definitely come soon.
@@edupoint.physics please sir give me the link.
Thanks sir
Sir kya aapne physics se phd kre h .. really great teaching, sir keep it up
Sir one more request take live class so that we can clear our doubt directly by you ... Please sir ..
jaruri nhi ki har Ph.D karne wala aise talent rakhta ho... Ph.D to just documents se mil jati h...

Very nice explanation sir ji
I'm also a physics lecturer
Hello Nikhil Ji,
Thank you for your appreciation.
It is an honour for me.

Cyclotron ke explanation ka bhi ak video bnao sir
???
@@edupoint.physics A cyclotron is a type of compact particle accelerator which produces radioactive isotopes that can be used for imaging procedures. Stable, non-radioactive isotopes are put into the cyclotron which accelerates charged particles (protons) to high energy in a magnetic field. ( from Google)
Iska working explain kijiye sir.🙂❤️

Good lecture sir
Hello Jainendra,
Kaise hain aap??
@@edupoint.physics sir aapke aashirvad mai bilkul theek hu
Sir agar app sach me physics ko love karte ho to reply me ! Jab badalo se bijli girti hai to ek type ka electric current nikalta hai then how electricity can travel through atmosphere and reaches ground?????⛈️🌩⚡? How ??u will reply if u r lover of physics like me!
Sir quantum mechanics kya hota hai??
Sir is it known as corona discharge....??
In which institute you study in Msc. Pls tell
Sir what is mean by only potential
