V

Volt (V) / ボルト (V):

 Unit of electromotive force. It is the difference of potential required to make a current of one ampere flow through a resistance of one ohm. / 起電力の単位。 1オームの抵抗に1アンペアの電流を流すのに必要な電位差。

Voltage / 電圧:

 The term most often used in place of electromotive force, potential, potential difference or voltage drop, to designate electric pressure that exists between two points and is capable of producing a flow of current when a closed circuit is connected between the two points. / 起電力、電位、電位差、または電圧降下の代わりに最もよく使用される用語で、2 点間に存在し、閉回路が 2 点間に接続されているときに電流の流れを生み出すことができる電圧を指します。

Voltage Breakdown / 絶縁破壊:

 A test to determine maximum voltage across an insulated wire before electrical current leakage occurs through the insulation. / 絶縁体を介して電流の漏れが発生する前に、絶縁されたワイヤの両端の最大電圧を決定するテスト。

Voltage Rating / 定格電圧:

 The highest voltage that may be continuously applied to a wire or cord in conformance with standards or specifications. / 規格または仕様に従ってワイヤまたはコードに継続的に印加できる最高の電圧。

Voltage Standing Wave Ratio (VSWR) / 電圧定在波比 (VSWR):

 The ratio of the maximum effective voltage to the minimum effective voltage measured along the length of a mismatched radio frequency transmission line. / 不整合な高周波伝送線路の長さに沿って測定された、最大実効電圧と最小実効電圧の比。
