Current of 4.8 amperes is flowing through a conductor. The number of electrons per second will be

A

`3xx10^(19)`

B

`7.68xx10^(21)`

C

`7.68xx10^(20)`

D

`3xx10^(20)`

Text Solution

Verified by Experts

The correct Answer is:
A
Current `="charges"/"time"="ne"/1`
`rArr" "4.8=nxx1.6xx10^(-19)`
`rArr" "n=(4.8)/(1.6xx10^(-19))`
`rArr" "n=3xx10^(19)` electrons/s
