Question

A conductor having same material.. 1st conductor length 2m and cross section area 4m sq.. Second conductor length is increased to 2times.. What will be the resistance???

Answer 1

Explanation:

as the length increases resistance also increases as they are directly proportional

the area increases then the resistance decreases

as they are inversely propotinal

so, in first conducter the resistance is remains constant

as in second conducter the resistance increases as the leangth is increased

hope this may help you
