Question

what happens to the resistance of the material if it's length is doubled and area is reduced by half?

Answer 1

Answer:

its resistance will fourth of the initial

Answer 2

Answer:

l-2l

A-A/2

resistance =resistivity (length) /area

then R=2l/A/2(if resistivity is constant)

R=4l/A

so resistance will increase by 4times

I hope this answer helps to you
