Translation guide
The English word "resistivity" is a technical term primarily used in physics and electrical engineering to describe a material's inherent opposition to the flow of electric current. This guide focuses on the core scientific meaning and its natural Japanese equivalents.
The measure of a material's ability to oppose electric current, typically denoted by the Greek letter ρ.
The standard technical term for electrical resistivity in physics and engineering. It is the most common and precise equivalent.
銅の抵抗率は低い。
The resistivity of copper is low.
この材料の抵抗率を測定する。
Measure the resistivity of this material.
An alternative term for resistivity, often used in geophysics and some engineering contexts. It is synonymous with 抵抗率 but less common in general physics.
Explicitly means 'electrical resistivity'. It is used when distinction from thermal or other resistivities is needed, but it is redundant in most contexts.
電気抵抗率の温度依存性を調べる。
Examine the temperature dependence of electrical resistivity.
In English, 'resistivity' is an intrinsic property, while 'resistance' depends on geometry. Japanese makes the same distinction: 抵抗率 (resistivity) vs. 抵抗 (resistance). Do not confuse them.
地盤の比抵抗を調査する。
Investigate the resistivity of the ground.
