Question

Чему равно сопротивление при поперечном сечении. срочно

Answer 1

R=(p*l)/S 
p - удельное сопротивление 
l - длина проводника 
S - поперечное сечение

Answer 2

Resistance in Cross-Section

The resistance in a cross-section is determined by the formula R = ρ * (l / A), where R is the resistance, ρ is the resistivity of the material, l is the length of the conductor, and A is the cross-sectional area of the conductor.

This formula indicates that the resistance is inversely proportional to the cross-sectional area of the conductor. In other words, as the cross-sectional area increases, the resistance decreases, and vice versa.

Is there anything else you would like to know about resistance or any related topic?
