Question

dharavahik Chalak ke andar electron ki gati hoti hai​

Answer 1

Velocity of electron will be $v_d=\frac{i}{neA}$

Explanation:

Let n electron is flowing on the conductor due to which i current is generated.

Let the area of cross section of conductor is A

And velocity of electron is $v_d$

Current flowing in the conductor is given by $i=neAv_d$, here n is number of electrons, A is area of cross section, e is charge on electron and $v_d$ is velocity of electron

From the above relation velocity of electron will be $v_d=\frac{i}{neA}$

So velocity of electron will be $v_d=\frac{i}{neA}$
