I Help with this static electric question

  1. Jul 5, 2017 #1
    What is the magnitude of the static charge induced on a circuit board when a human touches it? I mean approximately.

    Assume a few pF of parasitic capacitance and a few kV of voltage induced by the static discharge from the human to the PCB. Do you know the equation for the charge in terms of the capacitance and the voltage? :smile:
