The current in the conductor is 10 A. Find the mass of electrons that have passed through the cross section of the conductor in 1 hour.

To find the mass of electrons passing through the cross section of the conductor under consideration, we will use the equality: n * e = m / m0 * e = q = I * t, whence m = I * t * m0 / e.

Variables, constants: I – current strength (I = 10 A); t – elapsed time (t = 1 h = 3600 s); m0 is the mass of an electron (m0 = 9.11 * 10 ^ -31 kg); e is the electron charge (e = 1.6 * 10 ^ -19 C).

Calculation: m = I * t * m0 / e = 10 * 3600 * 9.11 * 10 ^ -31 / (1.6 * 10 ^ -19) ≈ 205 * 10 ^ -9 kg.

Answer: The mass of electrons is 205 * 10 ^ -9 kg.
