The strength of the current in the conductor I 10 amperes What is the mass of electrons passing through

The strength of the current in the conductor I 10 amperes What is the mass of electrons passing through the cross-section of this conductor for a time t is equal to 1 hour.

I = 10 A.

q = 1.6 * 10 ^ -19 Cl.

t = 1 hour = 3600 s.

N -?

According to the definition, the current strength I is the ratio of the electric charge Q passed through the cross section of the conductor to the time of its passage t: I = Q / t.

The electric charge Q, which has passed through the cross-section of the conductor, is expressed by the formula: Q = N * q, where N is the number of electrons passed, q is the charge of one electron.

I = N * q / t.

The formula for determining the number of electrons will take the form: N = I * t / q.

N = 10 A * 3600 s / 1.6 * 10 ^ -19 C = 225 * 10 ^ 21.

Answer: N = 225 * 10 ^ 21 electrons passed through the cross section of the conductor.
