I did my FSc in 2003. Still our education is far behind the modern techniques. I think in this practical, rather than adopting the most fundamental methods, we need to adopt modern meters to calculate resistance. In FSc, we should introduce microcontrollers and integrated circuits, because we are living in satellite and 5g age but our education is living in radio era.
@@yahyaafzal9274 i am not able to blame education system of pakistan ......i think you are a non sense person ......open your mind before your mouth please ................physics practicals have no benefit .....practicals is only a formality of pakistan education system ..........🙄
@@muhammadrazaansari3344 I think you are missing the fundamental theory behind this practical. This practical is used to teach the students how to calculate resistance of a wire between two points WITHOUT drawing any current from it. It teaches them that using a multimeter does not accurately show resistance of a circuit. A 'modern meter' will only give an estimated accurate value. That value might be accurate up to a few decimals depending upon the programming of the circuit, but will never be entirely accurate. However, using a slide bridge or wheatstone bridge, the only error we face is observational error. So instead of claiming that "physics practicals have no benefit", why don't you "work on it" as @yahyaafzal9274 has suggested.
Mashallah Sir, your teaching method is excellent... I hate practicals because our teacher doesn't explain it very well but I understood your explanation easily.... JazakAllah
Yar idher sir ne resistance find ki na..... Phir specific resistance ka formula laga de gein..... Wire ki lenght scale se measures karenge...... Screw guage se diameter find karenge.... 2 se divide krde radius.... Phir area ka formula laga deinge
Asslamualaikum!!!!! You literally explain so well that I understood each and everything......Literally I am saying I didn't understand in our practical class in college but after watching this video my all doubts just fly away.... Thank u so much for making such a wonderful video...... دیل سے شکریا
Thank you very much, you really helped us a lot. The physics sir in our school did not explain it and we did not perform the practicals, but thanks to you, I will inshallah ace the practicals now.
Thank you brother for explaining it well because at the first time I thought that I will never understand these practicals and I will fail them but now my hope rises thank you brother again May Allah bless you with all the happiness in the world Ameen
