An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?

Asked by sydjablonski09

Answer (2)

Changing the volume of a gas affects its pressure due to the principles described by Boyle's Law, where decreasing volume leads to more frequent molecular collisions resulting in increased pressure. Conversely, increasing volume decreases pressure as collisions become less frequent. Understanding this relationship is crucial in various scientific and practical applications. ;

To find the number of electrons flowing through a device, we first calculate the total charge using the formula Q = I × t . With a current of 15.0 A for 30 seconds, we find the total charge to be 450 Coulombs, which corresponds to approximately 2.81 × 1 0 21 electrons. Therefore, about 2.81 sextillion electrons flow through the device during that time.
