Atoms also collide with free electrons so that will also affect the resistance In my book it is written that the by increasing the cross sectional area resistance decreases because the electrons get more space to move but the number of electrons and the atoms should also increase by the same proportion and so the number of collisions i.e the resistance should remain the same
Sir make a full detail video on Ac and Dc current because mein kabhi samajh hii nhi paya ki current two types ke kaise hote hai? And Ac current kyu Ek wave ki tarah travel karta hai uper niche? Please sir bahut confusion but mein sikhna chahate hu please ek video isper banaiye yaa toh mujhe acche se explain kar de abhi 😢😢😢
sir..i have a question..that RESISTANCE also depends upon "nature of material" or not as my tutior tought me that RESISTANCE depends upon 4 factors 1:length 2:area(cross section of conductor) 3:nature of material and last 4:temperature.. but your are saying that RESISTANCE depends upon only 3 factors..iam so confused sir....😳
Sir when we increase the cross section area of wire to uske andar atoms bhi to bdenge.... He ... Aur collision bhi hoyega bcz of it's solid nature atoms are tightly packed toh fayda kya hua patle and mote wire ka
In class 12th, you will study about crystal structure properly. More surface area leads to free flow of electrons. so electron flow easily and resistance decrease
Thank u so much. Actually I tried during last year in lockdown. But i had no tripod at that time. So ,dil m uthal puthal si thi ki video record ho pa rha h ya nhi.
yes. It is forth factor. Resistance depends upon resistivity which is a proportionality constant and depends on the nature of material and temperature.
Atom aur electron mai collision nhi hota eletron electron ek dusare ko oppose karte h jisske karan cirrent ke flow mai paresani hoti h wahi resistance hota h

wow amazing sir..my confusion clear on resistivity and cross sectional area....thank you for uploading video
Please share with your classmates also😊
OMG is 10 min ke video me itna accha explanation thanqu thanqu very much sir 🥰🥰🥰🥰
Thanks ji. Most welcome ji. Plz share with your classmates
Mashallah sir ab samjh me aaya me ne self se boht try keya tha pr samjh me nae aaya lekin ab AAya thank you sir
TQ so much sir
You are really a good teacher
You lifts the calls at anytime for solving our douts 🎉❤😊

Sir aapka explanation bahut accha hai ham class 10 me padhte hai sir, class 10 ka " magnetic field of electric current" pe video laye

You are right! The analogy is wrong
Thnx sir
sir thanks for this topic but I have small suggestion that is look at the cam while explaining
Thank u so much. Actually I tried during last year in lockdown. But i had no tripod at that time. So ,dil m uthal puthal si thi ki video record ho pa rha h ya nhi.
Nature of material is also responsible....
yes. It is forth factor.
Resistance depends upon resistivity which is a proportionality constant and depends on the nature of material and temperature.
Thanks sir 😄
Nice try sir
Sir dependence of resistance with length of wire ke case me do relation hai 1) r ∞ l² and 2) r ∞ l
Sir please tell konsa relation kab use krte hai
Only Second relation is right. First is wrong my dear
I think you saw wrong formula. I think you are talking about R is proportional to square of n while we have relation R= (ro ) Ln^2 /A
Okay sir thanks

Sir formule me ro kya lagaya
Constant h na
I want an answer???
You r also right
Sir wo r ke sath dash kyu aya 8:53
Maine initial resistance ko R dash assume kiya h aur final ko R. Ratio V/I resistance ko banaata h.
@@PHYSICSCLASSES2018 sir assume hi karna hai kya isme kuch smjhne wali bat nhi hai kya
Wow . Amazing lecture video. Plz give your no.i want to ask some more doubts.
