+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Vd=(eE/m).T
Isko thoda modify kar lo and you'll see
Since radius is same so area will be same to charge densities ke ratio me area cancle ho jaega to Q1/Q2 ka ratio aajaega ab q kese is formulae me banau?
Wait for a bit
Mai thoda kar leta hun
oky
Is it C?
@Real potato
Current will be same cuz connected in series so im thinking I = Vd.e.n.A
density and no of electrons per unit volume would be same (ratio)
Yes ye wala lagega
My logic.
i = venA
Current is constant because conservation of charge. A is constant because same radius.e is charge on electron
v1/v2 = n2/n1
Yes c
Sorry I didn't figure it out earlier 'cause aise questions kiye time ho gaya thoda 😅
Yeah same thing, cancel out same terms which are I, e, and A, and yeah key is that n1/n2 = d1/d2.
You werent able to arrive on this above relation? @Real potato
Thank you guys i understood @KaiZên @Varun_Arora @Opt
This is the working out of that formula from the general drift velocity expression
If you want*
I didn't have an eraser so I just cut the mistakes out 😅
Ya i got it
