    If a current of 0.5 ampere flows through a metallic wire for 2 hours, then how many electrons would flow through the wire?
    Ans : I = 0.5 A

    t = 2 hours = 2 × 60 × 60 s = 7200 s

    Thus, Q = It

    = 0.5 A × 7200 s

    = 3600 C

    We know that number of electrons.

    Then,



    Hence, number of electrons will flow through the wire.
