    Answer:

    1.0625×10¹⁹ electrons

    Explanation:

    From the question,

    Using,

    Q = It…………………… Equation 1

    Where Q = charge, I = current flowing in the wire, t = time (seconds)

    Given: I = 1.70 A, t = 1 Seconds.

    Substitute these values into equation 1

    Q = 1.7(1)

    Q = 1.7 C.

    But,

    1.6×10⁻¹⁹ C = 1 electron

    Therefore,

    1.7 C = 1.7/(1.6×10⁻¹⁹) electrons

    = 1.0625×10¹⁹ electrons

    Hence, 1.0625×10¹⁹ electrons flows through the wire per seconds.
