If a current of 0.5 ampere flows through a metallic wire for two hours, then how many electrons flow through the wire?

Explanation

Time for which current is passed = `2 xx 60 xx 60 `seconds
Quantity of current =` Ixxt= 0.5xx2xx60xx60=3600C`
Number of electrons that flow when 3600 C of current is passed
= `6.02xx10^23 xx 3600/96500=2.24xx10^22`
