How does the "Pi" come in the equation of Resistivity ? Why use a 4 point probe ? How does 4 point probe method ensure contact resistance of probes do not come in measurement ? Thanks.

Nice video, just make sure you don't confuse the units next time onwards :P

[@pradyumnmattu9041]

you saved me thanks

[@santoshkm3678]

according to your readings the energy band gap is 0.11ev or 11.6ev(approx) but the energy band gap for germanium is 0.66ev i want to know the reason behind it.please state me if i am wrong

[@gaurangkuksal]

The readings should be taken for high temperatures (140-200°C), then the graph becomes linear at high values which yields a perfect slope

Yess srm ..Great work bro ... Srm guys rocks... I am also studying .. ..very helpful bro nice

[@akashsinha8933]

that will help for sure...thanks

[@MusicStringLovers]

thank you for this video. 😭😭

[@deanzantony9261]

you guys are from SRM right?

[@kaadshah7737]

SORRY BUT what is SRM?

[@deanzantony9261]

SRM university?

[@randomnessawkwardness3817]

yes this is SRM XD

[@protonsingh7332]

yes

[@prajjwaljaiswal6068]

Ya I think too

[@vinodmore9514]

very nice explaination of four probe experiment

[@ujjwalgahlot2877]

constant CURRENT of 2 miliVOLTS.@3.20...:p

[@TheSaptek]

Bro! Is that really your voice in English?

[@aadityajaiswal2300]

Is it srm lab

[@keerthivirat4653]

thank you so much

[@raiganjsquad4097]

What is use of ×10 switch?

[@devotedmind7805]

Can you send a copy of your practical ..which you shown in video

[@kenkaneki4305]

Gud explanation but at least hold the camera straight.

[@GauravSharma-tf7vx]

3:21 not mill volts its milli ampere

[@paras8361]

nice accent though!!!!

[@itachi_u0068]

It's enough for practicals

[@nitinyadav3352]

thank you brother

[@anshulbhargava4816]

nice video.going to help me in my models and sems.

[@airaliii]

hi, can u show me how u calculate the resistivity¿

[@riffeeaftab9869]

Thank you

[@ManishKumar-eg7ke]

Nice !!

[@airaliii]

Hi, may i know if it requires to do coding for this experiment. If yes can i have the coding script

[@mannugaming6378]

No

[@fatimarizvi2489]

Name of practical book plz

[@poojaparjapat910]

Sir plz tell how we connect wires ....

[@PSTWFB]

Four probe resistivity measurement! does ln and log mean the same thing! g7(w/s)!

[@shubhamrawat3079]

which mic do you guys used for recording this stuff????

[@amritjyoti3797]

BOYA

[@GPS_INNOVATIVES]

Which college are you in sir?

[@KRIITHIKSIVAPRASAD]

this video is shot in SRM university

[@shru_k]

thanks:-)

[@bhavnamehra7499]

Thnk you sir

[@dhanush_reddy]

Connections chupista cheyandi sir next ve annnna

[@Sagardeep_Das]

AAA battery sent me here. Only legends will understand this. 😂

[@known878]

U mean Aman bhai Alakh sir and whose third one?

[@sarveshvishnu]

Decent explanation. Lots of white noise and disturbances. Kindly improve the quality.

[@roshnimajumdar9058]

You should have taken few more readings.

[@arjunm631]

Plz share the pdf of your file 👀i will give you 100$ for this.plz share pdf of your file

[@mahendrabirla8192]

3:21 milli ampere

[@nilargharoy8810]

The camera sound was so annoying. :|

[@soumya9734]

that fake accent lol

[@sirsusgamer]

ok bro

[@athiraathi7815]

Why do you care.. just learn what they say

[@gautomdeka581]

What does it matter, it sounds good, I ain't got no problem with it

[@gautomdeka581]

And why the hell Indians care about accent I don't give a damn about it

[@VENKATESHSADU-s1o]

srm ???

[@laks-v3m]

how you know

[@angelapal3046]

Too much poor

[@ruffzi5786]

lmao SRM

[@RajeshDas-nl7xq]

Fake accent 😂lol

[@anureetkaur8481]

Why so fake accent? Indian accent ain't bad... So be proud of that instead of adopting this fake one...

[@umangpurohit5106]

Truee bro 🙌🏻

[@gokuldasari5238]

.

[@sourabhsinghyadav5637]

Fake accent

[@PlayDontStop]

Fake Accent......

[@Sam_Rao_23]

Why the fake accent bruh?

[@mishra.prateek]

Fake Accent.
