The whole idea of delivering these online lecture is to
-Provide a free facility to those students who might not have resources to engage with well known Expensive Physics Teacher
-Place a Conceptual Teaching Trend in Pakistan.
These lectures can also be delivered to those students who doesn't have internet facility (in Pakistan), if you know any of these students let us know, we will deliver them by ourselves.
Hope you enjoy doing Physics while watching these lectures.

Sir agr current x-axis pr bana dein tou wrong hojyga? Hamary journal me current ko x-axis pr banany ka likha huwa hai..

Khan Muhammad Affan Sir actually i was draw the graph in exam which was held today.. I confirmed to sir that it is right or not... He said it us right But you draw current on y-axis.. So i'm confused now Which is right

Uzair_ Ismail x-axis pe conventionally hum hamesha independent quantity ko consider kartay hain... If you are pre engineering student then you must have read y(x) which means y depends upon x... To isi liye y is always dependent quantity and x is independent... Ab is experiment me hum distance change kar rahay hain or uski wajah se current change horaha hai... To its mean current is dependent upon distance (or intensity) ... To kisko x-axis pe ana chahiye? And I didn't get k aap k Sir ne aisa q kaha...

Khan Muhammad Affan Sir Graph tou mera straight line hi arha tha.. Sir mujhe laga k current independent hai wo is liye k humne apne pas se current ki values likhi thi... Ab kya hoga 😥😥 No. Deduct hongy 😥😥

Khan Muhammad Affan sir mi ny graph bna kar uss py 2 points bhi plot ke jo aap ny Newton's law of cooling mi karwaye the... To mi ny apni teacher ko dikhaya orr mera graph bilkul sahi gaya orr apni friends ke bhi Help ke Thanks alot sir thumbs up👍

Mean distance nikala ga increasing distance and decreasing distance k (d1+d2)/2 is tarha d ajai g or uska square(d^2) nikal k inverse karla (1/d^2)

@khan_affan 2 жыл бұрын

Choose any one point (other than your observation) from the line on the graph, from that point draw a line that is perpendicular to x-axis (that will be your 1/d^2) take its inverse (this will be your d^2) and from same point draw a line that is perpendicular to y-axis (that will be ' I ' current). Then you can calculate I x d^2. One may need to prove I x d^2 is a constant, so you have to do the same with at least 2 different points.

Jee blkul... Actually shaid wo har saal pucha nahi jata isi liye reh gaya... Sorry for that... Karna ye hai k graph ki jo line draw karein gy uspe kahin bhi ek jaga se ek vertical line draw karein jo seedhi x-axis pe perpendicular jaa kar lagay... Phir jahan se line start ki thi usi point se ek horizontal line draw karein jo seedhi y-axis pe perpendicular ja k lagay... Ab ek ulta 'L' ban gaya hoga... Now check x ki kis value pe wo line arahi hai wo aap ki 1/d2 ki value hojaye gi or ab ye y-axis pe kahan arahi hai wo aap ki current I ki value hojayegi... Dono ko multiply karein... Ye kaha jata hai I x 1/d2... Yehi same kaam ek baar or line pe kisi or jaga karein... Bus is baat ka khayal rakhein k ye kaam line pe kahin bhi karlein but jin reading k points hain unse hat k hona chahiye... Ye kaam maine Newton's Law of Cooling k graph me kiya hai wahan se bhi idea hojayega... I hope clear hoga still confusion ho to puch lein
