Understanding Static Charge on Circuit Boards: Magnitude & Human Touch

AI Thread Summary
The discussion centers on the magnitude of static charge induced on a circuit board when a human touches it, with an emphasis on understanding the underlying physics. It suggests that the static discharge can involve a few picofarads of parasitic capacitance and several kilovolts of voltage. The relationship between charge, capacitance, and voltage is highlighted, indicating that the charge can be calculated using the appropriate equation. Participants are encouraged to explore existing resources for more detailed information. Understanding these principles is essential for managing static electricity in electronic environments.

hi there
you have given your topic an I level indicating you have undergrad university study level
what have you done so far researching this topic ?

there is masses of info on the netDave

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:
 

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
