Answer:
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. ... The resistance of a conductor, or circuit element, generally increases with increasing temperature.

Answer:
Resistance is Inversely proportional to cross sectional area..
i.e., R = pl
A
where, A is area of cross section
Explanation:
this is because, if area of cross section increases, there will be more area for flow of electrons in the direction opposite to current.. and thus resistance (opposition of flow of electrons) becomes low.
