Question

a conducting wire of cross section area 0.6 mm square carries a current of 0.4 A if the drift velocity of the electron is 5.4 × 10 ^-3 m/s calculate the number density of electrons in a conductor​

Answer 1

Answer:

USE THIS RELATION::

I = Vd e n A where Vd is drift speed , A is area , n is the number density of electrons
