An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The term 'in-network' refers to healthcare providers that have agreements with insurance companies to provide services at reduced costs. Choosing an in-network provider typically leads to lower out-of-pocket expenses. It's essential to verify if your provider is in-network to maximize insurance benefits. ;
In this situation, a device delivering a current of 15.0 A for 30 seconds allows approximately 2.81 x 10^21 electrons to flow through it. This is calculated using the relationship between current, charge, and the charge of an electron. The total charge delivered during this time is 450 coulombs, which corresponds to the total number of electrons calculated from their individual charge.
