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

Asked by lakeshiamcfarland

Answer (2)

A proton is a positively charged subatomic particle found in the nucleus of an atom and has a greater mass than an electron. It is attracted to electrons, not repelled. Thus, the statement that correctly describes a property of a proton is that it has a positive charge. ;

A current of 15.0 A for 30 seconds results in a total charge of 450 coulombs. This charge corresponds to approximately 2.81 × 1 0 21 electrons flowing through the device. The calculation involves using the relationship between current, charge, and the charge of a single electron.
