Question

If a body gives out 10^9 electrons every second,how much time is required to get a total charge of 1c from it?

Answer 1

Answer:

6.25 ns

Explanation:

We know Q=ne

where Q = Total charge

and n = no of electrons and e = charge of electron

So, Q= 10^9 e Columb

(by putting the values of n = 10^9 electrons)

So 10^9 e C is given by a conductor in 1 sec

then, For 1C charge the time required by the conductor will be

= 1/[10^9 e]

= 1/ 10^9 ×1.6 × 10^(-19)

= 10^10/1.6

= 0.625 × 10^10

= 6.25 ns or nano sec. ans.
