Question

Write a relation among resistance length and area what happen when length is doubled length is half areas doubled area is half to the resistance

Answer 1

Explanation:

The formula between resistance length and area is

R = Rho (l/a)

so R is directly proportional to resistance and inversely proportional to area

If length is doubled resistance is also doubled

if length is half then resistance is also halved

if area is doubled resistance is halved

if area is half resistance is doubled
