Calculate the number of electrons passing through the cross-section in a metal conductor in 1 s

Calculate the number of electrons passing through the cross-section in a metal conductor in 1 s at a current of 0.8 μA. (e = 1.6 * 10 ^ -19 C)

These tasks: t (the duration of the passage of electrons through the conductor) = 1 s; I (current strength) = 0.8 μA (0.8 * 10 ^ -6 A).

Reference values: e (electron charge) = 1.6 * 10 ^ -19 Cl.

The number of electrons passed in 1 s through the cross section of the taken metal conductor is determined from the equality: n * e = q = I * t, whence n = I * t / e.

Let’s perform the calculation: n = 0.8 * 10 ^ -6 * 1 / (1.6 * 10 ^ -19) = 5 * 10 ^ 12 electrons.

Answer: 5 * 10 ^ 12 electrons will pass over the cross section of the taken metal conductor in 1 s.
