An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
A device delivering a current of 15.0 A for 30 seconds allows approximately 2.81 × 10^{21} electrons to flow through it. This is calculated using the formula for electric charge and the charge of a single electron. By multiplying the current by time and dividing by the charge of an electron, we determine the total number of electrons.
