An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To calculate the number of electrons flowing through an electric device with a current of 15.0 A for 30 seconds, we first calculate the total charge using the formula Q = I × t , which gives us 450 coulombs. We then find the number of electrons by dividing that charge by the charge of a single electron, resulting in approximately 2.81 × 1 0 21 electrons. This illustrates the relationship between current, time, and charge in a circuit.
