Do sophonts on this list agree that AC current is more dangerous than DC cu= rrent ? >From =85... http://www.brighthubengineering.com/power-plants/89792-ac-and-dc-shock-comp= arison/ =3D=3D Let-go current is the highest current at which subject can release a= conductor. Above this limit, involuntary clasping of the conductor is pres= ent. It is 22 mA in AC and 88 mA in DC. =3D=3D Low frequency AC is more dangerous than high frequency AC. =3D=3D DC current will make a single continuous contraction of the muscles = compared to AC current, which will make a series of contractions depending = on the frequency it is supplied at. In terms of fatalities, both kill but m= ore milliamps are required of DC current than AC current. Is it agreed that electrocution ( stoppage of the heart ) is about the amou= nt of current delivered through the heart ? And here is is a question I have =85.. experiments have passed current thro= ugh the human brain to erase memories =85. and to restore it =85.. At the a= ge of 63 I can vividly recall events from 40+ years ago. Are these memorie= s a real copy of what I experienced at the time or a mash-up of stuff over = the intervening years ? gus in Denver =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
