A device delivering a current of 15.0 A for 30 seconds will have approximately 2.81 x 10^{21} electrons flow through it. This is calculated by first determining the total charge using the formula Q = I × t, then converting that charge to the number of electrons. Understanding these calculations helps grasp how electric current relates to the flow of charge.
