How many electrons pass through the cross-section of a metal conductor every second at a current of 1.6A?

To find out the number of electrons that have passed through the specified metal conductor, consider the equality: n * qe = q (passed charge) = I * t, whence we express: n = I * t / qe.

Const: qе – electron charge (qе = -1.6 * 10 ^ -19 C).

Data: I – current in the conductor (I = 1.6 A); t – time interval (t = 1 s).

Let’s make a calculation: n = I * t / qe = 1.6 * 1 / (1.6 * 10 ^ -19) = 10 ^ 19 electrons.

Answer: 10 ^ 19 electrons should have passed through the specified metal conductor.
