Question

to generate a charge of 1C, we remove 10^9 electrons/second from a body. find out how much time will it take to generate 1C of charge? ​

Answer 1

Answer:

Given,

10

9

electron takes 1sec

So, 1 electron takes →

10

9

1

sec

And we know, 1C=6.242×10

18

electron

∴6.242×10

18

electrons takes →

10

9

6.242×10

18

=6.242×10

9

sec

=

60×60×24×365

6.242×10

9

years

=197.93years

≃198years

If 10

9

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.
