If `10^(9)` electrons move out of a body to another body every second, how much time is required to get a total charge of 1 C on the other body ?

Explanation

If no. of electrons transferred from first body to second body in unit time is `N/t` then total charge transferred in t. time will be,
`Q (N/t) xx t. xx e`
`therefore 1 = 10^(9) xx t. xx 1.6 xx 10^(-19)`
`therefore t. =1/(1.6 xx 10^(-10)) = 10^(10)/1.6s`
`therefore t. = 198.2` year
