电阻 Electrical resistance and conductance(重定向自Electrical Resistance)
![]() ![]() ![]() ![]() 在电磁学里,电阻(英文:Resistance)是一个物体对于电流通过的阻碍能力,以方程序定义为 其中, 假设这物体具有均匀截面面积,则其电阻与电阻率、长度成正比,与截面面积成反比。 采用国际单位制,电阻的单位为欧姆(Ω,Ohm)。电阻的倒数为电导,单位为西门子(S)。 假设温度不变,则很多种物质会遵守欧姆定律,即这些物质所组成的物体,其电阻为常数,不跟电流或电压有关。称这些物质为「欧姆物质」;不遵守欧姆定律的物质为「非欧姆物质」。 电路符号常常用R来表示,例: R1、R02、R100等。

Electrical resistance and conductance 电阻(重定向自Electrical Resistance)
![]() ![]() ![]() ![]() The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction. The SI unit of electrical resistance is the ohm (Ω), while electrical conductance is measured in siemens (S). |
