Approximately 2.81 × 1 0 21 electrons flow through the device when a current of 15.0 A is delivered for 30 seconds. This is calculated by first finding the total charge using the formula Q = I × t , and then converting that charge into the number of electrons using the charge of a single electron. Thus, using these principles helps in understanding the flow of electric charge in circuits.
