To calculate the number of electrons flowing through a device that delivers a current of 15.0 A for 30 seconds, we first find the total charge using the formula Q = I × t . The result is 450 C , and dividing this by the charge of an electron yields approximately 2.81 × 1 0 21 electrons. Thus, 2.81 × 1 0 21 electrons flow through the device in that time frame.
