Excellent, far better quality explanation than a college teacher

Four probe resistivity measurement! does ln and log mean the same thing! g7(w/s)! kzbin.info/www/bejne/sJ_CqHR6iLehpMU

[@phmast92]

Thanks a lot for you

[@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

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.

[@VivekKumar-zh6og]

Thankuuuuuuuuuu ❣️

[@kikidwiwulandari7788]

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??

[@zahidurrahman-hp4sk]

today is my viva sir😂❤

[@sukhmansahi4358]

Why we use constant current instead of constant voltage power supply

[@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.

What are the values of G7,W,S?

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