Answers were Sorted based on User's Feedback
resistance of wire is inversely propotional to Diameter or area
thats why resistance will reduced by four times if dia increased

Answer / subrat
R = ρ * l / A , where R = Resistance ; ρ = Resistivity ; l
= Length ; A = Ar. of cross section.
It increases with the increase in length & reduces with the
increase in cross-sectional area.
