…The value of electrical resistance is proportional to the length of the conductor and inversely proportional to the cross-sectional area. At a constant temperature, the value of electrical resistance per unit length and unit cross-sectional area is determined by the material, and is called specific electrical resistance, resistivity, or resistivity. Its reciprocal is electrical conductivity. … *Some terminology explanations that mention "resistivity" are listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…電気抵抗の値は導体の長さに比例し,断面積に反比例する。一定温度では,単位長さ,単位断面積当りの電気抵抗の値は物質によって決まっており,これを比電気抵抗,比抵抗,あるいは抵抗率resistivityという。その逆数が電気伝導度である。… ※「resistivity」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
