NEET Physics Ohm's Law MCQ Question
What is the expression for drift velocity of electrons in a conductor?
v_d = -eEτ/m
v_d = eE/m
v_d = -mE/e
v_d = E/mτ
Correct Answer
Detailed Explanation
The drift velocity v_d is given by the equation v_d = -eEτ/m, where e is the charge of the electron, E is the electric field, τ is the relaxation time, and m is the mass of the electron, as stated in the NCERT context.
