Question

plzz tell that R=R/4 kese aya phir from photo​

Answer 1

R = ρL/A

yeh formula diya hua h ok

abh isme yeh bhi bola gaya h ki... ρ and A constant rahenge... this mean agar baki quantities ko agar hum change karenge to inke upar koi effect ni padega ..

abh L ( length ) ko four parts me divide kar diya... aur formula m yeh vi dekh skte ho ki L , R ke directly proportional hai... so jitna L increase karoge utna R increase hoga... or jitna L decrease karoge utna R decrease hoga...

yeha par L ko 4 times decrease kiya so R bhi 4 times decrease ho Gaya

So yeha PAR R/4 aaya

Thanku ☺

have a nice day !!^_^
