Dear Student

The relation between the resistance of a wire and its area of cross-section can be defined as:
R is inversely proportional to the area of cross-section [ R praposnal 1/A ]

It is inversely proportional to the area of cross section of the wire. The more the area of cross section of the wire,the less is the resistance and the less the area,the more is the resistance.
