The current in the circuit is 0.5 amperes. How many electrons will pass through the cross section

The current in the circuit is 0.5 amperes. How many electrons will pass through the cross section of a conductor in one minute?

To determine the number of electrons that have passed through the cross-section of a given conductor in 1 minute, we use the equality: I * t = q = n * e, from where we express: n = I * t / e.

Constants and variables: I – current in the circuit (I = 0.5 A); t – elapsed time (t = 1 min = 60 s); e is the electron charge (e = 1.6 * 10 ^ -19 C).

Calculation: n = I * t / e = 0.5 * 60 / (1.6 * 10-19) = 18.75 * 10 ^ 19 electrons.

Answer: Within 1 minute, 18.75 * 10 ^ 19 electrons will pass through the conductor.
