Hello sir g theory v mention kro na
Practical copy m mention krna hota
And thank you for clear explanation

[@nikhilnegi9446]

How do we find the magnetic field due to solenoid? Do we use direct formula or some practical method?

[@AllLabExperiments]

Use gaussmeter. That is thw only way. Or you may use a technique that is usually used in e/m but when mag field is quite low. Other wise hall effect or gaussmeter are the only methods.

[@aniruddhiitb4108]

Thank you so much sir

[@sheetalsharma8333]

Why Gussmeter show some value even when no current is applied?

[@AllLabExperiments]

Gaussmeter sensor is not something which is absolute. Depending on surroundings at ur home you have electricals wire, earth,s magnetic field which is very low in this case, are responsible for this. So we calibrate it by making it zero. And then start our measurement

[@iam_pi]

nice presentation and explanation ,Thank you

[@AllLabExperiments]

My pleasure 😀🙏

Sir if the sample will be Ge crystal of n type then will slope be also negative?

[@ushabajpai8834]

Amazingggg😊

What is e value in last slide

[@AllLabExperiments]

Charge on the electron in Coulomb. 1.6x10^-19 C

[@rachitsuthar9144]

How to know the nature of charge carrier

[@AllLabExperiments]

The sign of hall voltage changes with the change in charge carrier... In its viva voce video i think i have mentioned this question properly

[@rachitsuthar9144]

@@AllLabExperiments if hall voltage is negative then there negative charge carriers?

[@AllLabExperiments]

@@rachitsuthar9144 if every thing is correctly set in ur apparatus by convention then it means it is an n type semiconductor. Electron is the main charge carrier.

[@aritraghosh6660]

Why do we use a current source and not a voltage source????

[@AllLabExperiments]

Because we want a constant current... Even with the variation of temp...

[@sahil_gupta15]

Where is the detailed observation table sir? Readings

[@AllLabExperiments]

In description, you will find the link of my website and many related files with readings on the link.

Ok thank you sir!🙂
