if 109 electrons move out of a given body to

Question

If 10⁹ electrons move out of a given body to another body every second, how much time is required to get a total charge of 1C of the other body?

------------------------------------------------------------------------------------------

Defined q= n x e

here q=6.25x10^-18

and given that 10⁹ electrons.

so the time is required is 6.25x 10^-18 x10x(9)=6.25x10⁹

=6250000000 seconds

=104166666.666666667 minutes

=1736111.1111111 hours

=72337.96296296 days

=198.186199899 years.
