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

Asked by priscilla529292

Answer (2)

The total charge delivered by a current of 15.0 A over 30 seconds is 450.0 C. Using the charge of an electron, approximately 2.81 x 10^21 electrons flow through the device during that time. This calculation helps understand the relationship between current, time, and charge at the electron level.

Aerobic respiration requires oxygen, yields 36-38 ATP, and includes the citric acid cycle and oxidative phosphorylation, while anaerobic respiration does not need oxygen, generates only 2 ATP, and involves fermentation. Understanding these differences is essential for studying energy metabolism in living organisms. ;
