Can static go upto 20k?

  1. Mar 16, 2014 #1
    i heard that when we rub a finger on a nonconducting material 20000v gets generated,we don't get electrocuted because of low current.is that true?....really 20k?..
    i got a earful when i touched a smd ic from my professor,thats why i had this doubt....so any help please??

    It's a little more complicated than that. You can build up a static charge on your body equal to thousands of volts depending on the conditions you're in. See the following PDF for some basic ESD safety. I found this online by searching for "static discharge", so there is a wealth of info out there if you want to look it up.

    Static electricity voltages can go much higher than 20 Kvolts. Van de Graaff generators can go as high as 20 MV (20 million volts) and produce artificial 'lightning' bolts.
