Vedclass · Answer

(B) When an electric field $E$ is applied to a metallic conductor,the free electrons experience an electrostatic force $F = -eE$ in the direction opposite to the electric field.Since the electric field points from higher potential to lower potential,the electrons are accelerated towards the higher potential.However,due to continuous collisions with the positive ions of the metallic lattice,the electrons do not move in straight lines but follow random,curved paths between successive collisions.On average,they exhibit a net drift velocity towards the higher potential region.Thus,the motion of free electrons between collisions is along curved paths.

If the ratio of the radii of two wires of the same material is $1 : 2$ and the ratio of the current flowing through them is $4 : 1$,what is the ratio of their drift velocities?

Assertion: Free electrons always keep on moving in a conductor,even then no magnetic force acts on them in a magnetic field unless a current is passed through it.
Reason: The average velocity of free electrons is zero.
