Respected sir kya aap statical physics ke bus besic vidio upload kar sakte hai aap ke explanation amazing hote hai bus sir aap thoda sa help kar dijiye phir hum book se bhi padh lenge please sir

[@EngineeringPhysicsbySanjiv]

Busy in some other work now.. will try to do it later..

[@nitinlakkoju2418]

Well explained watching this before exam day can we attempt in paper sir

[@EngineeringPhysicsbySanjiv]

Watch in advance.. revise notes before exam

Sir plz tell me why we kept current constant when we want to determine energy gap of semiconductor??

[@EngineeringPhysicsbySanjiv]

I think your question s not related to this video. As I understand it is in regard of four probe experiment to determine resistivity and energy gap of semiconductor. In Four Probe experiment, the voltage across the inner two probes is noted at different temperatures. This voltage can be used to calculate resistivity when V is proportional to resistance which is possible only when current is constant. This is why a constant current is necessary.

Sir dynamic physics ke liye koi channel suggest kardo please sir

[@allrounders1296]

Sir what is active material in Ruby laser..... Sir plese bta dijiye

[@EngineeringPhysicsbySanjiv]

Cromium ions are active centres. In Al2O3, some Al ions are replaced by Cromium ions

[@allrounders1296]

Sir to chromium ion hi correct h ???

[@EngineeringPhysicsbySanjiv]

Xenon lamp is used for pumping cromium ions to excited levels
