Why resistance is directlyproprtional to are of cross section and inversly proportional to length of conductor?

Answers

Answered by Anonymous

The resistance of a current carrying conductor is inversely proportional to the area of cross section of the conductor. ... When area of cross section of the conductor increases, the gap between electrons increases. So the probability of collision decreases. As a result the resistance decreases.
