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

Text Solution

Verified by Experts

`Q=ixxt`
`=0.5xx2xx60xx60`
=3600 C
1F =96500 C is equivalent to flow of 1 mole of electrons
`=6.023xx10^(23)` electrons
`therefore` 3600 C is equilvalent to flow of electrons =`(6.02xx10^(23))/(96500)xx3600`
`=2.246xx10^(22)` electrons
