Best video , 👍👍 although I must say your all videos are superb atleast we are able to perform experiments in lab after watching them. 👍👍👍👍❤️❤️

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

sir, if i set constant voltage power supply, but i don't know how much the current. i only have constant voltage power supply and potential difference by the time. how i can calculate the resistance??

[@ghaziaman8072]

Thankyou man 🌺

[@HPGamer428]

Colling ke time voltage kaise check karni hai oven ki supply band karke aur current constant krenge toh voltage bhi constant hoga jb pven suplly of hai jb temp increase hoga voltage decrease hogi why voltage decrease

[@sukhmansahi4358]

Why we use constant current instead of constant voltage power supply

[@zahidurrahman-hp4sk]

today is my viva sir😂❤

[@shwetagupta1329]

What is w in this experiment?

[@SciPhy_Anurag]

Sir, what about the constant (c) of straight line equation, here ln ρ' .
How to measure it??
Sir please explain

[@AllLabExperiments]

Just take natural log of conductivity and plot it with respect to 1/T and then calculate the slope.

[@mrgreen3195]

Sir? Can I just take the cooling voltage for a sloped graph?

[@AllLabExperiments]

Yes... Heating and cooling curves may produce sligh differwnt reaults but yes both can be done.

[@user-wi8ic2us3l]

What are the values of G7,W,S?

You can't find band gap by this formula without multiple 2.3026
