# Can an electric circuit board have more electrons than protons?

Current flows from $+$ to $-$ but electrons go the opposite direction.

When I connect the GND of a positive charged electric circuit board to earth, then the board accepts electrons from the earth until the board is neutral.

But let's look at another situation where

1. the GND of a neutral board is not connected to anything

2. I am negatively charged, after rolling and jumping on the carpet for a while

(1) What happens when I touch the $GND$ of the board? Will the board accept extra electrons from me until the board and I are at the same potential. (Both negatively charged.)

(2) If so, what happens when I stop touching $GND$ and I connect GND to earth again? Then, can the board donate the extra electrons back to earth? Isn't there a lot of circuitry (like diodes and stuff) controlling the direction of current towards $GND$ and (since electrons go the opposite direction) thus preventing the electrons going towards earth?
