  Solution:
  
  Concept:
  
  Electric Current (I):
  
  • It is defined as the net amount of electric charge that flows through a cross-section of a conductor in an electric circuit in a per unit time.
  • S.I unit of electric current is Ampere(A).
  
  1 Coulomb (C):
  
  • One Coulomb of charge is equal to the charge transported by an electric current of constant magnitude in one second of time.
  • It is defined as the product of a 6.24 × 1018 ​charge of an electron.
  • It is the S.I unit of electric charge.
  
  Charge of one electron = 1.6 × 10-19 Coulomb.
  
  Explanation:
  
  We know that e = 1.6 × 10-19 C, i.e charge on the electron.
  
  The total charge required is 1 Coulomb, q = 1C
  
  Therefore we also know that q = n × e, (n = number of electrons on the charge)
  
  Hence, n = q/e....(1)
  
  Substituting all the values in the equation (1)
  
  n = 1/1.6 × 10-19 ​= 625 × 1016
  
  So, if 1A current flows through the conductor then 625 × 1016 electrons flow per second across the cross-section of the conductor.
