Edit: great approach to understand the matter: https://youtu.be/BGD-oSwJv3E?is=Fe1FimqTCvN-aY1u
I was looking at some transformers:
But also
If it outputs 12VA (12V * 1A) of apparent power, then it receives/works with (?) 12VA apparent power. That means that the current in my 230V wall outlet is 12 / 230 ≈ 0.05A. Even a button cell can supply 0.15A per hour… This leads my uninitiated head to believe, that it is mainly high voltages that are not compatible with life.
Please advise? 🙃
No. They ARE NOT decoupled. At all. Period. Unless you’re an idiot in today’s world.
While 12v can struggle to kill someone, it still can.
While 120v isn’t the end of the world, it’s still FULLY capable of murdering you depending on how the current flows.
The real answer is, and ONLY is, “it depends, and you do not like the answer”.
MANY shitty power supplies are FULLY capable of killing a human. The real question is: does your local government properly regulate things? (the answer is NO for 80%+ of the population, including americans)
