Задача 30629.

With a uniform build-up current in the conductor from the zero values \u200b\u200bfrom 0.5s through its cross section S = 10 m ^ 2 was the charge q = 17, Cl. Determine the average drift velocity of electrons in the maximum current density is achieved if the concentration was 8.5 * 10 ^ 28 m ^ 3.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
