Question

if the length of the conductor is halved.what will be new resistance?​

Answer 1

Answer:

then resistance also get half

Answer 2

Answer:

Let R = Resistance

ρ = Resistivity

L = Length in meter

A = Area

Then

R = ρL/A

Now new length = L/2

New Resistance =

R' = ρL/2A

or, R'= R/2

So the new resistance will be halved
