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

Asked by melvavelma51

Answer (2)

A current of 15.0 A for 30 seconds results in a charge of 450 C . This charge corresponds to approximately 2.81 × 1 0 21 electrons. Thus, about 2.81 × 1 0 21 electrons flow through the device.

One Coulomb of electrons per second is One Ampere.
One Coulomb = 6.241 x 10^18 electrons
SO:
6.241 x 10^18 * 15 * 30 = 2.81 x 10 ^21 electrons ;
