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
@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
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🙏☺️
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

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

You'll get 25 above because school wants to maintain its reputation too best of luck

Good
thankyou sir! i am watching this before my mock practicals and now i can say metre bridge is easy!
Only legends like whose watching one day before their practical exam 2024 attendance lagao
We use constanatan and maganin because their resistivity is high and temperature coefficient of resistivity is low

experiment cleared sir 👍👍
Aap to ekdum Kamal hai sir ...🔥
Thanks a lot
Sir amazing!!! Thank u so much
Those who are watching in 2024 attendence plz so i dont feel alone
Lode npc do ur work there
Sir bahut acha explain Kara thank you very much ❤❤😊
Very helpful sir 👍
Nice explanation sir
You are very good teacher thanks sir❤

Thanks beta 😊
Sir you saved my life.for me i dont know hindi eventhough the way you teaches is really interesting and im ready to do the practicals
We use constantum wire beacause it has high resistance and very low temp coeff

Please anyone who knows just give a reply below, do it as soon as possible
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
Thank u so much sir for this wonderful video✨👍🏻👌🏻
Constantan because of High Resistivity and Low Temprature Co-efficient.
Its really helpful for us thank u so much sir🤗🤗🤗
Constantan/ maganine and nichrome wire use in meter bridge because their resistivity is high and temperature coefficient of resistivity is low .
Thank you sir 😊🙏🏻.
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
We use manganin as is has high resistivity and low temperature coefficient or resistance
thank you sir😣😣😣
Present sir @Divyansh Mishra
Those who are watching in 2024 attendance plz 😂😂😂😂
🤣🤣🤣🤣🤣🤣🤣🤣
Thank you sir app Ki wajah se mere sare practical ho gaye
Sir because constantan or magnanin offer high resitivity and low temp coefficient//
How to use 1.2 ohm resistance sir
Thank you very much sir 😊😊😊😊😊
Because sir constantan or magnetisan ki resistivity high hoti and unki temp coeff of resistivity low hoti hai
1:00 because sir its resistivity is high and tem coefficient of resistivity is low
I have a suggestion, sir please avoid these many cuts during building the circuit.
Tday is my board practical at 11:30 am and i m watching at 10 am
Thankyou so much sir😍
Here one night before Physics Practical Exam which is on 10 Feb 2023. 😁
Sir why you are not using commutator and rheostat ? For direct current and reverse current?
Thankyou very much sir

Thank you sir
sir in experiment paper we have also these things only ,
Tomorrow is my exam and today I am watching this 😆
we use constantan and manganin because of high resistivity and low coefficient of temperatures
thank you so much sir
thank you sir 💙
Constant and manganin is used because they offer high resistance and low temperature coefficient of resistance
How do we measure value of resistance in points?
did you find find out?
we use manganin so that it offers high resistivity and lo tempraturre coefficient
Today is my practical exam n I'm revising by seeing this video thank you sir❤
Thankuh sir❤️
Supb vid 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?)
pta hi nahi chala 12th nikal gyi this might be the last time me ye dekh raha hu
Anyone watching in 2025 for boards practical 🎉
I only want to study how to fill observation table except this you told everything 😅
Any legend visit this for practicals.
Ha Mera kal hai🤓
Constantan and manganin are used because they have low temperature coefficient of resistance
Thnx a lot sir
We use cobstantant and naginin because they have high resistivity and low temperature cofficient
Ayeinn
2024 practical wale attendance lga do
We use constantan or manganin as they have low temperature coefficient of resistivity
👍
Because they have high Resistivity and low temperature coefficient ( magnanin and constantin )
❤❤
Bhai kal exam hai, thank u..!!!
Sir is writing the way you have written the practical on thay sheet sufficient for boards practical?
Sir 1.2 ,1.6 ohm resistance kaise kiya aapne ?
take the mean of the resistance
love u sir g
It really helped me thanks a lot sir🙌🏻🙌🏻
Any pro Max legend who is watching 1 hour before their pratical exam!!!!
I'm on the way to bus watching this lol
Thanku sir
Because constantan wire offer high resistance to the circuit and temperature coefficient offered is low
Sir you are telling that deflection must be in opposite direction but other teachers said that deflection in same direction
We use Constantine and manganese on that wire because it's resistivity is high and the temperature coefficient of resistivity is low
Batch 2024-25❤❤
Temperature of resistance cofficient is low
👍
Best video ever in practicals
Peoples watching just before practical day
Thank you sirrrr

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
A big thankyou from the depth of heart...really thanksalot🥺
