Detailed Solution

If a steady current of 1 A flows through a conductor for 1 s, then the number of electrons that passes through the conductor is 6.25×1018.
It is given that the current flowing in the circuit I=1 A for time t=1 s.
It is known that the charge is equal to
      q=It=ne
It=ne
n=Ite
n=1×11.6×10-19
n=6.25×1018 electrons
Hence, the number of electrons that passes through the conductor is 6.25×1018.
