Potentiometer Working Principle
The potentiometer consists of L which is a long resistive wire and a battery of known EMF V whose voltage is known as driver cell voltage. Assume a primary circuit arrangement by connecting the two ends of L to the battery terminals. One end of the primary circuit is connected to the cell whose EMF E is to be measured and the other end is connected to galvanometer G. This circuit is assumed to be a secondary circuit. The working principle depends on the potential across any portion of the wire which is directly proportional to the length of the wire that has a uniform cross-sectional area and current flow is constant.

About Faculty-
Completed Bachelors and Masters from IIT Kharagpur. Having an experience of +3 Years in teaching I reckoned the urge within me to help students appreciate the subject by delivering the toughest concept in simplest manner through practical demonstrations and visual aids.

I was Always confused in this sub-topic but This topic got cleared Today. Thank you Bhaiya 🙏

[souquatraza]

Really...that stdnts who are unknown to ur channel are very unlucky😎😎 kya mst smjhate hai aap sir♥️♥️

[souravmishra]

yaar kui aise he chemistry or maths ke channel bata do 😭😭😭😭 sir you are the best

IIT-ek prem katha

Mai doond rha tha apne bhavishye ko
ki maine suna about jee
confidence aur pride ke chalte maine bola
hum bhi kar lenge iit

phir kiya join institute
starting me bada maza aaya
dosto ke saath padhke aur khake
1 saal maze lutaya

badme toota flow, aur man bikhra
socha kya hai iit, kyu hi mai kr rha
ek mahina yahi socha mai nikala
jab time kam pada, tabh mai bhaga

2 mahine me syllabus rush kiya
tension me har din roya
lecture pe lecture, dpp pe dpp karke
mano maine apna bachpan khoya

phir aaya jee mains,
subhe subhe utha aur gaya
exam ke saare questions khatam karke
mai dukhi hoke aaya

socha second attempt me phodunga
uske liye betha padne
ab lagi cheeze easy
toh maze wapis aane lage

second attempt ki baari aayi
mai chati chaudke paper likhne gaya
boht marks ka paper deke samaj aaya
ki cut off hi clear nhi hua

man hara, bhatke soch pe pada
zindagi pe full stop lagane ke khayal aaye
but yaad dilaya ki
ye sirf comma hai, full stop nhi

phir lagadi maine puri jaan for bitsat
2 mahine kuch nhi socha
abhi 4th hai, 24 ko exam
ye poem ka end, tabh edit karke hoga

zindagi mai aayengi dukhi, samasya aur peeda
lekin man ki aawaz sune waalo ko
milti hai inam ka phal meetha

-written and directed by a current BITSAT aspirant
Wheter i cleared or not will be known on 24, if you want to know just comment and i'll reply.



UPDATE: BITSAT first attempt finished and i got 231 marks. Isse kuch nhi milega. Trying my best for second attempt. please pray for me

[feabg]

1) done for bitsat
2) i think phir se dekhna padega for smooth solving
3) concept samajh agaya !
Thank u sir ! so grateful to be a part of ur community nd to be ur student!

[avichaltrivedi]

One thing will always remain constant for your channel sir, that whoever comes here with some hope never goes disappointed! Got my concept cleared and feeling confident. ❣️💯

[supreetfact]

Day 2/20 done sir
Thank u sir
Ab ja k samajh aaya potentiometer
M hmesha skip kr deta ye topic but Aaj iska mechanism pta chal gya thank you sir 🙏🥰🥰🥰

[luckylickykata]

Thank you very much sir... I am completing my pending topics one by one through these videos. 😊

[arpitanand]

Pranam sir 🙏🏻
Being a jee 2021 aspirant i wanna tell u that in my previous 3 attempts my overall best score is 99.7 percentile .. my percentile in physics is bit low coz i don't have knowledge abt optical instruments, electrical instruments, communication system and vernier calliper n screw gauge .. but this tym i have completed these topics with the help of ur videos nd i m damn sure that this tym i will get perfect 100 in physics nd u r the only person who deserve all the praise for it sir .. thank you so much ❤️ if i will get a chance to tell smthng abt my teachers on any platform .. u r surely gonna be there in physics field .. thank you sir

[parush]

thanks to bhahot chota shabad hai ...sir bhahot helpfful video tha...all concepts crystal

[swarnimsharma]

Crystal clear with this topic now...was facing trouble with this..it was taught to me like soo complicated...TYSM for this lecture sir
