An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To calculate the number of electrons flowing through a device delivering a current of 15.0 A for 30 seconds, we first find the total charge, which is 450 C. Then, knowing that the charge of a single electron is approximately 1.6 x 10^-19 C, we find that about 2.81 x 10^21 electrons flow through the device.
