what's the current of a static shock?

TimFox:
Technically, a static shock is a certain amount of charge, and the current is limited by the resistances discussed above.

Did you mean his videos reminded you of this thread so you bumped it?

What people forget, is that such 'low power' static charges VERY quickly collapse in voltage, due to their nature.
This often happens faster than any bodily response to such contact. And to others, 100-mA???... I don't know about
the USA, but Earth-Leakage Breakers here usually trip at about 20-mA, (very short duration!) as 30-mA will kill you!!

S. Petrukhin:
Static charge flows away at a speed close to the speed of light. The peak value, which decreases very sharply, obeys Ohm's law. These are very large currents, but small Coulombs (1 coulombs = 1 ampere per second). That is, the charge can perform very little work despite a very high voltage.

However, a static charge can damage without generating a current. p-n junctions are formed by doping: in one region there is a lack of electrons, in the second - extra ones. To damage the p-n junction, you can apply a current to mix these areas, but you can also apply a field. A rough example: you have a bunch of screws and nuts on the table next to you. You can mix them by pushing them with your hand-this is the current. But you can mix them without touching them with a magnet. A static charge can suck out electrons or put them where they don't need to be. This is how the electromagnetic pulse from a nuclear explosion damages semiconductors.
