A wire has a current of 6.0 mA in it. How many electrons pass a given point in a minute?

Question

Quizplus · Accepted Answer

The current is 6.0 mA, which is 6.0 × 10^-3 A. The charge of one electron is approximately 1.6 × 10^-19 C. The number of electrons passing a point per second is given by the current divided by the charge of an electron. In one minute (60 seconds), the number of electrons is (6.0 × 10^-3 C/s) × (60 s) / (1.6 × 10^-19 C/electron) = 2.25 × 10^18 electrons, which is approximately 2.3 × 10^18 electrons.
