An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To find the number of electrons flowing through an electric device with a current of 15.0 A over 30 seconds, we calculate the total charge as 450 coulombs. Dividing this by the charge of a single electron (1.602 x 10^-19 coulombs) gives approximately 2.8 x 10^21 electrons. Thus, about 2.8 x 10^21 electrons flow through the device.
