In a device with a current of 15.0 A for 30 seconds, approximately 2.81 x 10^21 electrons flow through it. This is calculated by first finding the total charge in coulombs and then dividing by the charge of a single electron. The formula Q = I × t helps in determining the total charge delivered over the time period.
