A compound of 電(でん) (electricity) and 圧(あつ) (pressure). The standard term for voltage in both everyday and technical contexts.

CULTURAL CONTEXT:
Japan uses 100V household electricity, which is lower than most countries (110-240V). This is a common topic for travelers and expats who need voltage converters (変圧器(へんあつき)).

COMMON COLLOCATIONS:

  • 電圧(でんあつ)が高(たか)い/低(ひく)い — high/low voltage
  • 電圧(でんあつ)を上(あ)げる/下(さ)げる — to raise/lower voltage
  • 高(こう)電圧(でんあつ) — high voltage
  • 電圧(でんあつ)変換(へんかん) — voltage conversion

RELATED TERMS:

  • 電流(でんりゅう) — electric current
  • 電力(でんりょく) — electric power
  • 変圧器(へんあつき) — transformer, voltage converter
  • ボルト — volt (unit)
