Note for OP
+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.small change is what they are saying
perhaps they use some mathematical tool that has approximations in the derivation
limits related
yeah but like if i want to derive it how do i?
yeah i thought something similar is there with some approximation we just say ok this is true
Poora page bhej sakte ho kya
I know how to derive it I just don't understand why R is proportional to l^2
Over here
Log se derive hoga btw
Ya bas differentiate bhi kar sakte ho
Isme log lekar differentiate karna padega
,rotate
upr question the
Accha accha
You know how to take log roghr
Right*
ys
equi ne sikha diya
Aur log ka differentiation bhi aata hoga
Badiya
nhi
kabhi try nhi kiya
Say logy ka differentiation hai
bas law padha tha 11th me
kabhi kiya nhi
Differentiate w.r.t x,
(1/y).dy
Haan basically wohi hai
Arey ye to error analysis se ho sakta hai
Haan wohi
Why do all fhis
Isme log ka kya kaam
Wth
Usme bhi toh log hi lete hain
koise?
Error analysis mei
What's all this
Aayein
Nahi
Lmao
Ruko bhejta hu
error me log?
hain?
:')
See write R = kl^2, k is constant of proportionality
Take log on both sides
LogR = logk + 2logl
Differentiate
dR/R = 2dl/l
Logk ka differentiation is zero
hain kya?
smj nhi aaya
Now you can see, if l is changed by x, R is changed by 2x
aap pen paper se bata sakte hain?
Haan aight*
R = rho L/A
Multiply both sides by L
Rho L²/V (V= AL)
Iske baad apna error wala
Del R/R = 2Del L/L
Volume will be constant
OHHHH AISE KARNA HAI??
Damn ok
Yea ig this is itt
Area wale mein area se multiply divide kardo
yaar aap pen paper kyu nhi use karta koi phy doubt me kabhi
meri itni buddhi hoti to mai smj nhi leti aise hi
Mai vacation mein hu bhai pen paper nahi rehta merepe
😭😭
are thik hai bhyi apka samj aata hai
Ek min
mere har doubt me they write on text like nhi bhyi mera itna dimag nhi ki mai aise smj paau
phy me to nhi
ji
Actually ye log se hi hota h derive
I remember maine iska poora derivation jeeneettards mein bheja tha bohot pejls
Pehle
bad server
Yes
,rotate
Haan same thing
I did
Since constant hai unme change is 0
And increase decrease is just agar change % +ve hai matlab increase
Bhejne ki zaroorat nahi hai
And change % -ve matlab decrease
hn itna pata hai
Understandable
isme apn 5% increase kaha liye?
ya mai pgl ho chuki hu
jyda phy karli hai
2% change in resistance for 1% change in length right
Nigga fym?
x<5 matlab small change hai
Isiliye ye formula lagraha hai
Basic maths padhlo
Please
ye language na yaha nhi chlega ok ?
i dont like to repeat
Padhai pe dhyan do
Moderation hojaaegi
Yesab basic hai
Aana chahiye acche se
Agar x>5 hoga fir kaise nikaloge ye bhi pata hona chahiye
dekho bhyi tumhe batana hai batao nhi batana mat aayo doubt kisi ke karne
