Question

26. Is there any relation between emf of
battery and drift speed of electrons in the
conductor connected to a battery ?​

Answer 1

Answer:

Drift velocity vd = V/(ρlne), where V is the potential difference, ρ the specific resistance, l the length of the conductor, n the number of electrons per unit volume of the conductor and e the electronic charge. (Emf is the p.d. when the cell is not supplying any current.)
