Irrelevant as what it isn't relative to is any part of your household wiring.
- grues-dinner 1y agoNeither is the output of an isolated power supply. That's the whole point. There is an enormous amount of resistance between the output side and the household wiring in the input side, just like the battery scenario. The difference between gigaohms (like you might see in between the windings of the SMPS transformer) and exaohms or whatever the airgap between the battery and the nearest outlet is is negligible for any practical purposes. You may see AC leakage due to the capacitance between the windings and also that of the Y capacitor (this leakage is the source of the sensation in the article), but that's also tiny and it won't be blowing up any crocodile clips. If you did have that happen, your power supply wasn't isolated somehow.
