An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?

Asked by pradipsutihar54

Answer (2)

To find how many electrons flow through a device carrying a current of 15.0 A for 30 seconds, we calculated the total charge delivered as 450.0 Coulombs. Dividing this by the charge of one electron, we found that about 2.81 x 10^21 electrons flow through the device. This step-by-step process illustrates how current relates to electric charge and the number of electrons involved.
