Question

Relation between resistance conductivity length and cross sectional area of a metal wire

Answer 1

Resistance=conductivity×cross section area÷length

HOPE IT HELPS

PLEASE MARK AS BRAINLIEST

Answer 2

♣️ AHOLA FRIEND ♣️

✅Here is your answer ✅

__________________________________________________

It is observed that resistance of a conductor is

⭐Directly proportional to its length

⭐ Inversely proportional to its area of cross section

So,

R= Rho × Length/Area

✌️Hope it helps you ✌️
