Question

what happens to the resistance of a conductor when its area of cross section is increased.... best answer will be marked as brainliest

Answer 1

Consider

Resistivity of the conductor = r

Area of the cross section of the conductor = A

Length of the conductor = L

Resistance of the conductor decreases when the area of cross section is increased. It is because

R = rl/A

Resistance is inversely proportional to Area .

So when area of cross section is increased resistance of a conductor will decrease.  

Answer 2

the resistance of the conductor decreases because the resistance of the conductor is inversely proportional to area of cross section. so when the area of cross section increases the resistance of conductor decreases
