Assume I put some electronic device, a laptop for example, in free space. Now add electrons to the object. It will become progressively more negatively charged. At what point will the laptop (or whatever) stop working, and what will be the failure mode?
When modeling electronic circuits using Ohm's law, capacitors, MOSFETs etc., the non-relative potentials are rarely considered significant, everything is calculated relative to some arbitrarily chosen potential. However, I assume this is a simplifying approximation/abstraction. At what point does this abstraction break down, and why?
I understand that if the laptop is nearby some earthed object, there'll be capacitive coupling and thus a mode of interference, but my question is about free space where there are no other objects near by.
Edit: The laptop has non-infinite resistance between all components and the electrons are added slowly.
