Question

1.Верно ли?Вследствие того, что электроны проводимости в металлах очень часто сталкиваются с ионами кристаллической решетки, их средняя скорость направленного движения мала.

Answer 1

Да верно. Скрость направленного движения электронов не превышает 1 мм/с при значительном значении силы тока 
I=qo*n*V*S
V=I/qo*n*S
I - сила тока
S - площадь сечения проводника
n- концентрация электронов проводимости

Answer 2

Veracity of the Statement about Electron Conduction in Metals

The statement that "due to the frequent collisions of conduction electrons in metals with the ions of the crystalline lattice, their average speed of directed motion is small" is true.

This phenomenon is a result of the interaction between conduction electrons and the ions of the crystalline lattice in metals. The collisions with the lattice ions lead to a decrease in the average speed of the conduction electrons.

The average speed of the conduction electrons is reduced due to the scattering caused by the interactions with the ions of the crystalline lattice. This scattering results in a decrease in the net drift velocity of the conduction electrons.

This behavior is a fundamental aspect of electron conduction in metals and is a key concept in understanding the electrical properties of metallic materials.
