Question

establish the relation between drift velocity of free electrons and electric current.....

Answer 1

relation between drift velocity and current is                                                                V(drift) =I/neA                                                                                                     where      I= current            A=area               e=charge of electron                                         n=no of free electrons per unit volume

Answer 2

Hey mate ☺️

$\huge \red {Ur Answer}$

fLet l is the length of the conductor and A uniforms area of cross-section. If n is the number of free electrons per unit volume of the conductor, then the total number of free electrons in the conductor=A/n. ... Hence the current flowing through a conductor is directly proportional to the drift velocity.

Hope it works♥️✌️
