The resistance of a conductor varies directly with its length, conversely with its cross-sectional area.
导体的电阻与其长度成正比，与其横截面积成反比。
The multifunction electrician tool of the utility model can measure the diameters of various conductor wires and can directly read data, such as the sectional area of a conductor wire, etc.
它不仅具有传统电工刀的功能，而且具有测量各种导线直径，直读导线截面积等数据的功能。
This shows that the resistance of an electric conductor is inversely proportional to its cross-sectional area.
这表明，导体电阻的大小与导体横截面的大小成反比。 收藏。
