To find the number of electrons flowing through a device with a current of 15.0 A for 30 seconds, we first calculate the total charge, which is 450 C . By dividing this total charge by the charge of a single electron (approximately 1.6 × 1 0 − 19 C ), we find that approximately 2.81 × 1 0 21 electrons flow through the device.
