Someone I know has a bathroom that is not GFCI compliant, and I was wondering if it is possible to have a shower that’s humid enough to allow electricity to transfer, or would at that point would the air be inhospitable to breathe in.
With high enough voltage everything becomes conductive.
ELI5?
This here is the Volt family.
Marty volt is small and so he can jump across a small stream. Put up a small net and it’s impossible for him
Victor, though. He’s got some strong legs. He can jump the net and the stream.
In fact, he’s so strong he can jump over a small river but not if you put a small wall across the way. Then, even with a running jump, he’ll be blocked.
And finally there’s Kal, ahem, Clark Volt. He’s super strong. So strong it could be an ocean and with a little jaunt before leaping he’d jump it.
The stronger the volt, the further they can go and the bigger the obstacle you need to make it impossible for them to make it.
So high enough voltage can literally leap through air (that’s the arcing you see in power plants shorting or lightning) or even wood itself. Even rubber, with a high enough voltage, will be conductive since the sheer force of the current will find a path for the charge.
That’s also why we have lighting rods, it’s easier to redirect the current to a safe spot made to handle it than to try and make high skyscrapers out of a material that can resist the insane charges of lightning and still be strong enough and light enough to build with.
This answer is great! Thanks!
Lightning is just air conducting electricity. Air is not typically considered a conductor.
Everything can have a positive or negative charge. Voltage is just the difference in charge between two points. Given a big enough difference in charge any material can conduct electricity to balance the charge since nature seeks to balance out differences in charge/energy.
He’ll, skipped that and hold the wire between two hands (don’t do that, it cannot be stressed enough how much of a bad idea that is. You wanna commit die? That is by far the most efficient way of doing it, so DONT)

Electricity almost always transfers through the air and along the surface of materials. Air is considered an insulator because it doesnt conduct electricity very well, but it essentially acts like a very, very large valued resistor.
Given the voltage, you can calculate the distance through air a spark can jump using the breakdown threshold for the air. This is the distance at which the air breaks down creating a lower resistance path which lets more current flow, resulting in a large spark. For AC wall voltage this distance is extremely small, and even 100% saturated air will still have an extremely small spark distance.
In other words the humidity isn’t directly a problem. The problem is condensation and corrosion, which could result in shorts, fires, and shocks, as well as electronics which fall into water or have a loose wire inside. Hair dryers, curling irons, etc can be dangerous because their heating elements can have live wires inside that could shock you if you dipped it in water. GFCI is meant to save you in cases like this by turning off the outlet.
Not on its own. You’d have much more of a risk of shorting out because the water condenses on all the surfaces.
Pure water is a fairly poor conductor, and the ions that make it conductive don’t always follow the water into the air.
You can force it to be conductive by using a high voltage current, but a high enough current will make anything conductive, given enough power, so that’s probably despite the point.
Short of super-saturating the air, it’s probably difficult, if not impossible to make it inhospitable to breathe in with eager vapour. Water can only hold so much, and while you can increase the amount it can hold by changing the temperature, you’d be overheating the the traditional way at that point.
Maybe some extreme super-saturation of the air, so the water condenses in the airways? Although that’s extremely unlikely, since it’ll probably condense on the rest of the person, and the available surfaces first.
ElectroBOOM has a good video related to your question. He’s demonstrating with a bucket of water rather than humid air but it shows what’s needed to complete the circuit.
Please do not try this at home.
that makes sense, that video was very educational, I didn’t realize that it wasn’t the water itself that was conductive but the contents in the water. Knowing that, it does make a bit more sense.
Yeah I remember when I learned about that and feeling like Pokemon had lied to me. Water isn’t weak against electric!
I love electroboom!
