Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting -50nC per step. What charge build up will a worker in a manufacturing plant accumulate if shewalks 23 steps? How many electrons are present in that emount of charge? And finally if a delicate manufacturing process can be damaged by an electrical discharge of 10^12 electrons, what is the max number of steps any worker should be allowed before touchingthe components?
