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

Answer

`2.246xx10^(22)` electrons

Explanation

`1F=96500C=1mol of el ectrons=6.02xx10^(23)`
`Q=Ixxt=0.5Axx(2xx60xx60s)=3600C`
`3600C` is equivalent to flow of electrons
`=(6.02xx10^(23))/(96500)xx3600=2.246xx10^(22)`electrones
