Question

If $10^{9}$ electrons move out from a body to another body every second, How much Time is required to get a total charge of 1C on Another body ?

Answer 1

Answer:

we know that 1 Coulomb = 6.242×$10^{18}$ eleCtrons

Given $10^{9}$ electrons take 1 secs

=> $10^{9}$ electrons ------> 1 sec

=> 1 electrons ---------> 1/($10^{9}$) secs

=> 6.242×$10^{18}$ ------> 6.242×$10^{18}$/ ($10^{9}$)

= 6.242×$10^{9}$ secs = 6.242×$10^{9}$/ (60×60×24×365)  years

=197.93 years

=198 Years
