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

Asked by jujubeans2007

Answer (2)

To determine how many electrons flow through the device, we first calculate the total charge using the current and time, which is 450 C. Then, dividing this by the charge of a single electron (1.6 x 10^-19 C), we find that approximately 2.81 x 10^21 electrons flow through the device. This provides a clear picture of the flow of electric charge in terms of electrons over that period.

The English horn is named due to a translation error from the French "cor anglaise," meaning English horn, and refers to its shape rather than being a true horn. While it looks similar to a hunting horn, it is a woodwind instrument, not a brass one. It became popular in England through its use by composers but is not necessarily an English creation. ;
