sir u are the most awesome and the best teacher i have ever encountered in my life. u sacrificed a lot just to become a teacher so thank you so much. by becoming a teacher and uploading these videos u have helped many people and i salute u for that. u are a true hero because u made me fall in love with physics again and u are a living proof that teachers are the block builders of a society. you teach physics so good that one thinks its too good to be true. thank you once again and God bless you.
Thank you very much for uploading these videos sir and by doing this you are helping many students and doing a great job. Again thank you very much. Thanks a lot.
Thank you sir.. just a few days before my exams your videos are the only hope i'm left with. And with every videi my respect for you moves to a next level altogether. Thank you so much sir .. I cant thank you enough. Thanks for doing all of this effort ☺ in this time when even our tuition teachers are selfish you do such a great job with such a selfless purpose. Thank you sir.. 😊
coil is fixed around the soft iron core . therefore when the cylinder moves the coil which is wrapped around the coil also rotates . hence both including cylinder move
To sir agar hum length ko increase ya decrease karte h to no. Of turns bhi increase ya decrease honge to esse hum ye bhi to kah sakte h ki voltage sensitivity no.of turns of coils per depend. Nhi karti h
sir, at 09:34 u said that magnetic field can never be intersect (they get turn) but at 14:09 in the diagram u interseceted the magnetic field , i m confuse , plsss help
Sir, in introduction, you have written “ a device to sense and measure electric current” - galvanometer Sir but ammeter is also a device to measure a current... When these both are same . Then why we needed a galvanometer..????
Sir I have a question. When we pass current through a conductor then a magnetic field is set up .In galvanometer we also pass current through the conductor. , which also establish a magnetic field .Does this magnetic field do not effect the magnetic field produced by the permanent magnets? Plz answer sir
Rizwan ghani Search on google by typing "calculation of torque". It shows an image. See that, you will understand very nicely. Also read the statement which is shown along with the image. I too had the SAME confusion. ☺
if the soft iron cylinder were removed (if the radial field were not present in the moving coil galvanometer) , then the torque would be BINAsin0 and I would be proportional to alpha/sin0. the scale would then be non linear and difficult to read/measure accurately.

it's a great job that you are helping a needy students by uploading videos
thank you so much
sir u realy creat my love with physics thanks alot for uploading this lectures
Thank you so much sir
Your teaching method is awesome.
Sir you are great teacher in the whole world there is no one likes you
Many many gun salute to ur teaching method......

Doesn't the anti torque developing on the spring at a certain instant reduce the original torque produced in the coil ?
Please Answer Sir!
scalar,vector and tensor quantities .current is tensor quantity

sir you are a legend of physics....
I am medical aspirant. If i get any medical college this will only because of u. You r d best.
In which college now you are??
fabulous sir...
thanks a lot
Sir bahut khatarnak padhate hai aap kisi bacche ko bhi samjh me aa jaega
Sir, can you please tell me that is only coil rotating or both including cylindrical soft iron core?
coil is fixed around the soft iron core . therefore when the cylinder moves the coil which is wrapped around the coil also rotates . hence both including cylinder move
I saw IIT lectures...that were all about the separation of core from coil...thats why I got confused....
awesome explanation
thanks a lot sir
@vineet kumar curent is tensor quantity
it is a tensor quantity because it is dependent on direction but doesnot follow vector law
bhai scalar hi padh na.......... cbse me aaj tak tensor word ka use suna hai?
PAPA Gee class 11.. Fluid mechanics (physics)
Please make a video for preparation ofneet also. About expecting questions
Please......

To sir agar hum length ko increase ya decrease karte h to no. Of turns bhi increase ya decrease honge to esse hum ye bhi to kah sakte h ki voltage sensitivity no.of turns of coils per depend. Nhi karti h
sir this coil is wound over the cylindrical core or fitted inside it?
Fitted inside
Great sir 🙏🙏
sir, at 09:34 u said that magnetic field can never be intersect (they get turn) but at 14:09 in the diagram u interseceted the magnetic field , i m confuse , plsss help
ankita varshney its not intersected when the coil is moving the magnetic field line also changes
ankita varshney vvv
sir can you please explain voltmeter and ammeter also?
Sir is the' i' in Is 45:22 unit current?

Sir,

Sir but ammeter is also a device to measure a current...
When these both are same . Then why we needed a galvanometer..????
to know vry xmal crrnt
It is used to measure very small amount of current
You r my inspiration sir
sir why u have used needle instead of mirror
Sir I want to see ballistic galvanometer practical please.......

sir plz electricity magnetism k liye easy wording book recomend kar dein plz.
Sir is ammeter ,votmeter not in course?
Thank you 😊😊
What comes the most from this chapter in boards??
awsome ........
Sir why is there a cos alpha in formula for torque?
sir current is tensor quantity or scalar quantity?
scalar qty.
VINEET KUMAR tenser bro has direction but disobey vector law same like pressure
tensor
no
Tensor quantity bro
Sir you are great
Galvanometer as voltmeter, ammeter kyu Nahi bataya ha......

Sir you didn't told anything about Figure of Merit!
Not in ncert
thank u so much sir
I want to learn about ballistic galvanometer
sir please explain me why do we say that radial magnetic field gives the linear current scale
actually what does it mean? please sir reply.
sir i really want to know may we write cos(theta) other then sin(theta) when we write mathematical form of torque?

Thanks Sheetal Pahadi
Thanks sir *****
yes we can use cos theta but in that case the theta will be between plane of area and B we will not use area vector
Tysm🙏🙏🙏
sir soft iron core hi kyu hotha hai
if the soft iron cylinder were removed (if the radial field were not present in the moving coil galvanometer) , then the torque would be BINAsin0 and I would be proportional to alpha/sin0. the scale would then be non linear and difficult to read/measure accurately.
@@aditisharma2742 idk but your language is that of SL arora lol no offence
Thanks guru g
🙏🙏🙏
galvanometer is a current detecting device?not measing device
💝👍
Thnks sir
🎉
sir aapke lectures to bhaut lengthy hai
THERE IS NO SHORTCUT OF SUCCESS
increase the video speed from settings and watch
Yes ur right
