An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The statement that relapse is an uncontrolled return to alcohol or drug use after treatment is true. Relapse is a common part of the recovery process and can be influenced by various factors like stress and triggers. Ongoing support is crucial for managing the risks of relapse. ;
When an electric device delivers a current of 15.0 A for 30 seconds, a total charge of 450 coulombs is generated. This charge corresponds to approximately 2.81 x 10^21 electrons flowing through the device. The calculation involves using the current and time to find the charge, and then dividing by the charge of a single electron.
