# 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. One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
