R= rho*l/a
where R is the resistance ; l = length ; a=Area ; Rho= resistivity
Directly proportional ; as the length of the wire increases , its resistance increases.
Why?
Simply speaking,the longer the distance the electron has to travel ,the more collisions it will face with the atoms ; which means higher resistance.
