There is a current of 5.0 A through an electrical device for 10 seconds.How many electrons flow through this device during this time? (e = 1.60 × 10^-19C) A)0.20 B)20 C)2.0 D)3.1 x $10^{20}$ E)31 x $10^{20}$

Question

Quizplus · Accepted Answer

To calculate the number of electrons flowing through the device, we can use the formula:

n = I * t / q

where n is the number of electrons, I is the current, t is the time, and q is the charge of a single electron.

Substituting the given values, we get:

n = 5.0 A * 10 s / (1.60 x 10^-19 C)
n = 3.125 x 10^20

Therefore, the number of electrons flowing through the device during this time is 3.1 x 10^20, which is closest to option D.
