Question:
It Is Said That Resistance Decreases With Increase In Area Of Cross Section But Increase In Area Of Cross Section Increases No .Of Electrons So How Does Resistance decrease
Answer:
Yes. Number of electrons does increase with the increase in surface area, but the understanding here is that the electrons have more area to move when flowing when area of cross section is increased. So the collisions with the metal atoms are less. As a result of this, the resistance is supposed to decrease.
