    An electron gun emits 2.0 ×1016 electrons per second. What electric current does this correspond to?
    Ans : Rate of emission of electrons = 2 ×1016 per second
    Total charge passing through the gun = 2 ×1016 ×1.6 × 10-19 = 3.2 × 10-3 per second
    We know:
    Current, I = rate of flow of charge
    ∴ I = 3.2 × 10-3 A
