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

Explanation

Coulombs of electrons = Current `xx` time
`= 0.5 A xx 2 xx 60 xx 60 s = 3600 C`
Now , the current of 1 F(96500 C) is equivalent to 1 mole i.e, `6.022 xx 10^(23)` electrons .
`therefore 3600 C ` of current is equivalent to flow of electrons
`= (6.022 xx 10^(23))/(96500) xx 3600 = 2.246 xx 10^(22)` electrons
