The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction.

電導 （英語： Electrical conductance）是表示一個物體或電路，從某一點到另外一點，傳輸 電流 能力強弱的一種測量值，與物體的 電導率 和幾何形狀和尺寸有關。 现在 国际单位制 对这个数值的单位为 西门子 （Siemens，缩写“S”，國際電導單位；等於歐姆的倒數） [1]。 在过去，电导的单位为「姆歐」（Mho，由Ohm即 欧姆 这个词的字母顺序颠倒而得，或以℧来表示）。 [2] 歐姆定律 是. 其中， 是 電壓， 是電流。 所以，可以得到 歐姆電導定律 的關係方程式： 請注意，當 阻抗 …

2020年4月22日 · What is Conductance? Conductance, or electrical conductance, measures a material’s ability to conduct electricity, essentially showing how easily an electrical current can flow through it. It is the opposite of electrical resistance, mathematically expressed as 1/R.

Electrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter σ (sigma), but κ (kappa) (especially in electrical engineering) [citation needed] and γ (gamma) [citation needed] are sometimes used.

2024年8月29日 · 电导率（electrical conductivity）或比电导（specific conductance），又译电传导性、电导系数，是表示物质传输电流能力强弱的一种测量值。 当施加 电压 于 导体 的两端时，其 电荷载子 会呈现朝某方向流动的行为，因而形成电流。

The conductance is the inverse of resistance. It is the allowance of the electrical current through a conductor, denoted by “G” and measured in Siemens represented by the symbol of “Mho” (℧).

电导率（electrical conductivity）或比电导（specific conductance），又译电传导性、電導係數，是表示物质传输电流能力强弱的一种測量值。 當施加 電壓 於 導體 的兩端時，其 電荷載子 會呈現朝某方向流動的行為，因而形成電流。

Electrical conductance measures how easily electricity flows through electrical components for a given voltage difference. The SI unit of conductance is siemens (the older unit was the mho). Generally, people prefer to think in terms of resistances rather than electrical conductance, although neither is actually more fundamental.

2023年9月4日 · Electrical resistance, simply called resistance, is a measure that provides information about the opposition offered by a material in the flow of current. On the other hand, electrical conductance, or simply conductance is a measure of ease with which the material allows the electric current to flow through it.

In an electrical circuit, the electrical conductance of a component is essentially a property of a component that describes how the current in the component is directly related to the electrical potential difference, or voltage, across it.
