Why is the electric resistance of a wire inversly prportional to itrs Ar of Cross_section?

Expert Answer
Let's consider few electrons that are flowing though a wire. If the cross sectional area is small they'll be crowded to move along, and if it's wide they can flow free without much collision with one another. This crowdedness or frequent collsions of these electrons among themselves and atmos is what we say as resistance.
Hence the eletric resistance is inversely propotional to the cross sectional area.
