							Dear student,

Charge passing the plane in each second=I
Therefore, number of electrons passing the plane in each second=\dfrac{I}{e}

Brother,
               Charge carriers are electrons  
      The equation represents that,
                  q=it and q=ne
              Thus, ne=it
 So,.        n= it/e
              According the question time t=1
        Hence,         number of electrons passing through out the plane each second = I/e
