I suppose it’s half right. Obviously OHMs law is the triangle.
So you get a high voltage, running through a high resistance, it won’t kill you. The problem is people interpret it in a way that seems to think raising the voltage without raising the resistance is just fine.
In static electric fields, sure. But the real world has rapidly changing electric fields, and mapping concepts like voltage or resistance to a time dimension starts to require imaginary numbers (and the complex analogue to resistance goes by a different name of impedance). And once you’re modeling electricity through those concepts, you can have high current in a particular moment in time where the voltage might not be high. Or where the implied voltage is very high but was actually more of an effect than a cause.
In other words, if you’re simply talking about “resistance,” you’re already in the wrong domain to be analyzing electrical safety properly.
I always thought that was a dumb saying because voltage is specifically what allows there to be a lethal current.
I think people just don’t understand ohm’s law. They seem to think voltage and current are unrelated to each other.
