A current of 5.0 A flows 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

The total charge (Q) that flows is given by Q = I × t = 5.0 A × 10 s = 50 C. The number of electrons (n) is Q/e = 50 C / 1.60 × 10^-19 C/electron = 3.1 × 10^20 electrons.
