One ampere and one second = electrons....

One ampere and one second =_______ electrons.

A

`6.25 xx 10^(23)`

B

`6.25 xx 10^(18)`

C

`6.25 xx 10^(20)`

D

`6.023 xx 10^(22)`

Text Solution

Verified by Experts

The correct Answer is:
B
1 amp `xx` 1 sec =1 Coulomb
1 F= 96500 Coulomb and `1F =6.022xx10^(23)` electrons
`therefore ` 1 Comlomb `=(6.022xx10^(23))/(96500)=6.25xx10^(18)` electrons
