Summary Of: High voltage

High voltage is used in... high voltage is usually considered any voltage over approximately 35... Accidental contact with high voltage supplying sufficent energy will usually result in severe injury or death... energy exposure to high voltage may be harmless... provides a high voltage pulse whenever the current is interrupted... A high voltage is not necessarily dangerous if it cannot deliver substantial... these machines apply high voltage to the body for only a millionth of a second or less... a close approach can be hazardous since the high voltage may spark across a significant air gap... to quench the arc when the high voltage circuit is broken... very high voltage can cause the electrical breakdown of such insulators...
