How many electrons flow when a current of 5 amperes is passed through a conductor for 200 seconds?

A

`6.02 xx 10^(23)`

B

`6.24 xx 10^(21)`

C

`6.024 xx 10^(21)`

D

`6.2 xx 10^(22)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Q="It"=5xx200=10^(3)C`
Since `6.02xx10^(23)` electrons flow when 96,500 C is passed
`therefore` Number of electrons
`=(6.02xx10^(23))/(96,500)xx10^(3)=6.24xx10^(21)`
