If a current of `0.5` ampere flows through a metallic wire for 2h, then how many electrons would flow through the wire ?

Explanation

`Q =ixx t`
`=0.5 xx 2 xx 60 xx 60`
=3600C
1F = 96500C is equivalent to flow of 1 mole of electrons
`=6.023 xx 10^(23)` electrons
`:.` 3600C is equivalent to flow of electrons `= (6.02 xx 10^(23))/(96500) xx 3600`
`= 2.246 xx 10^(22)` electrons
