1.
electrical conduction; electrical conductivity
The transmission of electrical current through a material. Used in physics and engineering to describe the ability of a substance to conduct electricity.
銅は電導率が高い。
Copper has high electrical conductivity.
この素材は電導性に優れている。
This material has excellent electrical conductivity.
超電導とは、特定の温度以下で電気抵抗がゼロになる現象のことである。
Superconductivity is the phenomenon in which electrical resistance drops to zero below a certain temperature.
A physics term composed of 電 (electricity) and 導 (conduct/guide). Often interchangeable with 伝導 in the context of electrical conduction, though 伝導 can also refer to heat conduction.
COMMON COLLOCATIONS:
- 電導性: electrical conductivity
- 電導率: conductivity rate
- 超電導: superconductivity
- 電導体: conductor (of electricity)
SIMILAR WORDS:
- 伝導: conduction (broader term, includes heat and electrical conduction)
- 導電: electrical conduction (alternate word order, same meaning)
- 通電: passing of electrical current (focus on the act of sending current through)
USAGE:
The compound 超電導 (superconductivity) is one of the most commonly encountered uses of this word. In scientific contexts, 電導 specifically refers to electrical conduction, while 伝導 is the broader physical concept.
