Sentence:  At 100 Amp the 360 cycle ripple was less than 0.5 <WSD>V</WSD> ( peak to peak ) with a resistive load . 
Meaning of the word marked with <WSD> tags:  a unit of potential equal to the potential difference between two points on a conductor carrying a current of 1 ampere when the power dissipated between the two points is 1 watt; equivalent to the potential difference across a resistance of 1 ohm when 1 ampere of current flows through it
