We only use constantin or magnanin wire the resistivity of these metals is very high and the temperature coefficient of these wires is very low (dependence of resistivity on temperature is very low). Thus their resistance does not vary with temperature.
We use constantant and manganin because it provides more resistivity but less temperature coefficient to reduce the heating effect caused by the wire while the current flows for a longer time
its morning 4:21 AM and today is my practical at 10:00 AM, entire year our school was dump and teacher also didn’t explain much about these experiments but now i am watching all your experimental videos, although i am not confident about full 30/30 but at least i will get 20 or 22 or whatever and all this credit goes to you sir, very very thanks sir, you saved my practical exams today🙏☺️
@learnphysicswithrktomar8633 sir hamare school ke sir bhi aapka video dekhke aae the to unhone humse poocha ki ise meter bridge kyu kehte he and unhone bola iska zyadatar answer galat hota he same aapki lines copy Mardi 😂and fir kabhi nhi btaya ki kyu bolte he kyuki aapne nhi btaya sir plz bataiye na kyu bolte he
We use constanatan and maganin because their resistivity is high and temperature coefficient of resistivity is low Btw thank you sir aap ne experiment bahut acha se explain kiya kal mera practical hain aur ab main confident feel kar raha hu
Thank you so much sir for this experiment. Our teacher told us to perform it ourselves and I felt stressful But after watching your videos I am ready for my practicals🎉🎊😊
Hey, why are the reading for the resistances in decimal, should the known resistance from the resistance box be an integer??? 4:41. Please anyone who knows just give a reply below, do it as soon as possible Sir, please answer... 👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇
Which is the correct equation to calculate unknown resistance X=R(100-L)/L or X= RL/100-L In some videos they say X=R(100-L)/L and in some other videos it's X= RL/100-L
During performing this experiment at times i get deflection of galvanometer on the same side.Why this is happening sir, not able to figure out, kindly help.
Very helpful even for 2024 board practicals, thank you sir 🙏

Because constantan wire offer high resistance to the circuit and its temperature coefficient for resistance is low so it expands less

You'll get 25 above because school wants to maintain its reputation too best of luck
How it was bro?
How did it went?I have practicals tomorrow

Thank s a lot sir this is best video for physics pratical.
0:59 because their resistivity is high and temperature coefficient of resistivity is low
We use Constantin or Mangnin wire because their resistivity is high and temperature coefficient of resistivity is low.
Correct 👍

Thanks beta 😊
How to use 1.2 ohm resistance sir
The best explaination of experiments
Sir amazing!!! Thank u so much
We use constantum wire beacause it has high resistance and very low temp coeff
Nice explanation sir
You are very good teacher thanks sir❤
Constantan because of High Resistivity and Low Temprature Co-efficient.
Thank u so much sir for this wonderful video✨👍🏻👌🏻
Thank you sir ❤️
Constantan/ maganine and nichrome wire use in meter bridge because their resistivity is high and temperature coefficient of resistivity is low .
Sir because constantan or magnanin offer high resitivity and low temp coefficient//
❤❤
Its really helpful for us thank u so much sir🤗🤗🤗
Sir vo calculation mein jo theoretical value of Rs h kya vo given hota h ya fir humme find karna hota h(agar humme find karna h toh kese kare?)
Because sir constantan or magnetisan ki resistivity high hoti and unki temp coeff of resistivity low hoti hai
Sir why you are not using commutator and rheostat ? For direct current and reverse current?
Watching in 2050 like .
sir in experiment paper we have also these things only ,

Sir, please answer...
👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇
Exactly what I was thinking
It's a small resistance box
@@ronakarun9932 still bro, how can it be in integer.?? i understand its a small R.B, so it can be 2, 4, 6... but 1.2, 2.2??? not possible imo
Which is the correct equation to calculate unknown resistance
X=R(100-L)/L or
X= RL/100-L
In some videos they say X=R(100-L)/L and in some other
videos it's X= RL/100-L
Happy teachers day sir . 😃💚

Thank you sir app Ki wajah se mere sare practical ho gaye
I have a suggestion, sir please avoid these many cuts during building the circuit.

Constantan and manganin are used because they have low temperature coefficient of resistance
we use manganin so that it offers high resistivity and lo tempraturre coefficient

During performing this experiment at times i get deflection of galvanometer on the same side.Why this is happening sir, not able to figure out, kindly help.
Then the things are not connected correctly you have done mistakes in the circuit
this man saved me
thank you sir 💙
Present sir @Divyansh Mishra
Because they have high Resistivity and low temperature coefficient ( magnanin and constantin )
Thankyou very much sir
A big thankyou from the depth of heart...really thanksalot🥺
lol ab to boards bhi over hogye hoge
Sir experimental value of R mein bohot difference aa raha hai
Thank you sir
Sir you are telling that deflection must be in opposite direction but other teachers said that deflection in same direction
Because constantan wire offer high resistance to the circuit and temperature coefficient offered is low
We use Constantine and manganese on that wire because it's resistivity is high and the temperature coefficient of resistivity is low
It really helped me thanks a lot sir🙌🏻🙌🏻
VERY GOOOOOOOD VIDEO
thank you so much sir
Bhai kal exam hai, thank u..!!!
