Arcing causes more fires, because over current caused all the fires until we tightened standards and dual-mode circuit breakers.

Now fires are caused by loose connections arcing, and damaged wires arcing to flammable material.

Breakers are specifically designed for a sustained current, but arcing is dangerous because it tends to cascade, light arcing damages contacts, leading to more arcing in a cycle.

The real danger of arcing is that it can happen outside of view, and start fires that aren't caught till everything burns down.

Huh, I didn't know the romans thought it was over.

Figured they'd think it was just not worthy of their attention at that moment.

We need better research into defensive technologies, to help Ukraine now.

There is no current without voltage, what you're saying makes no sense.

Current is voltage over resistance, you get as much current as you have voltage, unless there's an artificial effect limiting voltage, like a voltage regulator or zener diode or just fet.

When you say 'it's the current', that electric fense has x volts before you touch it, and the fact that it doesn't kill you means either the voltage is too low to produce a decent current in your body, or, there's a voltage regulator/limiter that means when you touch it the voltage drops to some lower level, which I could calculate using the nominal resistance of the human body and the voltage of the fence.

In a way, the output impedance of whatever is driving the fence determines how much the voltage drops under load.

I'm speaking about the voltage needed to get the deadly current across the critical areas of your body BTW, which can be handled as a kirchoff circuit I'm sure.

No it's not, I'm an ee.

P = I^2R, so power squares against the current, while it's linear to voltage.

This means current causes more heat dissipation in the wire, which has risks, potentially fire if you really go too far, this is why breakers trip.

But what really causes fires (again, outside of crazy overcurrent) is Arcing, from basically either bad connections or bad insulation, OR, from an inductive load that gets disconnected, so the current tries to stay constant in the coils, which leads to massive voltage spikes.

Omfg that is so bigoted!!!!

I'm not even white!

She was, but im not sure who would have been better.

And as I type that, I still think her girlfriend this season would have been better casting for her. As would Abby.

Yeah, in Sweden I charge our plug in hybrid off 240, it's pretty quick and you can use any outlet.

The giant round connectors are weird BTW, with all the holes, trying to sort that out for faster charging.

I don't think we should run 100+ volts everywhere, we need to standardize on lvdc in most places (basically usb-c or so) with 100v only in kitchens and places you need it, because it's more dangerous and can cause fires more easily.

Amps are voltage over resistance (I = V/R), volts absolutely matter, the human body has a decent resistance and the higher voltage helps burn through that.

Teump: "Aww, you're making me blush!"

Preach.
