    Given,

    109 electron takes 1sec

    So, 1 electron takes → 1/109 ​sec

    And we know, 1C=6.242×1018electron

    ∴6.242×1018electrons takes →6.242×1018​/109

    =6.242×109 sec

    = 6.242×109​/ 60×60×24×365 years

    =197.93years

    ≃198years

    If 109 electrons move out of a body to another body every second, then 198years is required to get a total charge of 1C  on the other body.
