Question

derive an expression for electric current in terms of number of electrons in a metallic conductor

Answer 1

actually the correct answer for this quetion is as follows :-

=> ne = q ---> 1
=> n = q/e ---> 2
therefore , electric current = number of electrons ( n = q/e )
time taken

Answer 2

ne = q ---> 1
=> n = q/e ---> 2
therefore , electric current = number of electrons ( n = q/e )
time taken
