Question

drift velocity of free electrons and its relation with current I=neAvd?
no silly answers please​

Answer 1

Answer:

Explanation:

Current density  J = I/A

Total number of free electrons =  nAL ( electrons per unit volume)

Total charge due to free electrons= nALe

I = q/t

I = nALe/t

I = nAe(L/t).         Where: L = distance

                            And.    T= time

                          Therefore distance upon  

                             Time equals to velocity

Hence I = nAevd
