電でん位い差さ

noun

potential difference; voltage

Physics/electronics term for the difference in electric potential between two points. Often used interchangeably with 電圧 (voltage), though 電位差 emphasizes the difference between specific points.

• 電でん池ちの両りょう端たんの電でん位い差さを測そく定ていする。

  Measure the potential difference across the battery terminals.

• 電でん位い差さが大おおきいほど、電でん流りゅうが流ながれやすくなる。

  The greater the potential difference, the easier it is for current to flow.
