Four Probe Method [EXPERIMENT]

[@solomonjoseph19]

I like the video. Very helpful

[@arijitRC473]

Sir, in my college when I did the experiment the temperature was getting increased.... But here it is getting decreased can you tell me why?

[@dhritishmanhazarika3894]

because he switched off the oven after it reached 200 degreee celcius

[@sujanhasanmiddya7118]

Why the voltage is decreasing and not increasing

[@saurabhsharma4261]

it is property of semiconductor due to band gab between conduction and valance band approximately 1ev ,as the tem. goes up the electron jumps to conduction band ,so the conductivity increases and voltage decreases

thank u very much very helpful video

thank you 😎

[@dhritishmanhazarika3894]

where are the references for the theories ?

Man why are all these 4-probe measurements videos using ancient equipment.
If yous want to know what is F and D, you just need to pay a one time charge of 199.99...
