Electricity and water

[stratus.vaping]

Electricity likes to take the route with least resistance. I'm sure that the VG/PG surrounding a coil does have some electricity flowing through it, but if you have a 0.2ohm coil it's going to go through it rather than the higher resistance liquid.

Absolute pure water has a resistance of around 18.0 megaohms (18,000,000 ohms) per cm. salt water iirc is something like 0.2 megaohms (200,000 ohms).

So e-liquid is going to be a much more difficult route for those rampant electrons than a subohm coil 8)

Exactly.

Electricity in a circuit always takes All Available Paths. But is does so Proportionally to the Resistance of the given Path.

Which is a Good Thing.

Because if electricity Only took the Path of Least Resistance, Dual Coil Vaping wouldn't be Possible.

LOL

Yes I agree. I said "likes" to take not "only" takes, I wasn't clear enough as usual 8) Some goes through the liquid, but it will be a relatively small amount 8) Tiny in fact.

I thought your Post was Good.

I just wanted to make Sure that people understood that there is Always electrical flow if it is Possible.

For something like this Water/e-Liquid vs Atomizer Wire situation, as you pointed out, there is such a Ginormous Difference in Resistances, that for all Practical intent, it is All going thru the Wire.

Or where the Resistances of Two Coils in a Dual Coil atomizer is basically the Same, Half goes down 1 Path and Half goes down the Other.

But for something like a "High-Low" Dual Coil set-up (something I experimented with Briefly) where one puts Coils of Different Resistances in an Atomizer (like a 0.5 Ohms Coil and a 1.5 Ohm Coil) then the flow is Split and is Proportional to the Deferential Resistances governed by a Kirchhoff's Law.

This vid covers electricity and water in an easy to understand manner

I don't know the science of it but I do know water can conduct electricity I mean did not your parents warn you about downed power lines and puddles?

IDK if you can get a serviceable vape out of water but the answer would be not with what equipment we have now.

And wouldnt our skin be of a higher resistance also? Like if you accidentally touched a live coil. Seems you would get a burn, but not really a shock

I know firsthand do not touch a power line. I took a shock of 8000 volts. It will disable you if you're lucky. Lost limbs if you're lucky. Do not touch any electric power lines. I learned the hard way.

Addendum where's my post?

 

[GOMuniEsq]

My theory is that any water that would short the electricity quickly vaporizes leaving the path clear.

Current = Voltage / Resistance

Our coils use a very low voltage (a single-digit number).

Our skin and body have fairly high resistance. How high depends on conditions (moisture, saltiness, etc). I just stuck the quite sharp probes of a multi-meter on my index finger, less than 1 cm apart. 4.5 mega-ohms.

Therefore the current flow is very, very low (micro-amps), which is too low to produce a "shock" of any kind.

Take a AA battery. Lick your fingers. Hold the positive with your thumb and the negative with your index finger. You have now completed the circuit. I guarantee you won't feel like you did.

Stand on a third rail of a train with both feet (at least have shoes on). So long as both are on the rail you're fine. Put one on a rail track and you're not.

Electricity will follow the path of least resistance. If two paths are if equal resistance to current flow it divides. It otherwise will distribute proportionally based on the difference in resistance. So long as you're not the "bridge" between a high voltage high Amp current and ground you're good. If in a high voltage high current situation (which we're not at 4V despite the Amp draw) you provide a pathway for flow you're in trouble. But with the third rail example all that current will flow through that nice thick rail rather than your body. Just don't step off one foot at a time.

And get off before the train gets into the station. It would suck to survive the third rail then get smacked by the subway car. And screw up everyone's commute if you insist on playing around during rush hour.

I can definitely "taste" a full 1.5V cell on my tongue. In fact, I've been known to test AA-D and even 9V batteries that way. A good, fresh 9V battery has a a lot of flavor!

Electricity will take the path of least resistance. I used water a few times to wash out a good coil after a failed new flavor attempt. I found the steam created with a quick fire with a damp coil cleans them up nicely. Then I air dried them 100%.

Another warning label seems necessary, for you and your kind:

 

[Tabac man]

As a kid I loved sticking my tongue on those little square batteries with both terminals on top. Loved the 'taste'.

 

[stratus.vaping]

PP9 9V batteries on the tongue were a favourite sick gag of mine many years ago, have two of identical make, one is flat the other good. Tell a mate, preferably gullible, that you don't think the battery is good and test the terminals on your tongue... palm that one and give him them the other to confirm. Guaranteed madness.

I can feel a fully charged AA on palm if the skin is sweaty, PP9 definitely, sweat is slightly salty so conducts better than dry or water damp.

BTW it's the current that kills ( a simplification but it's the essence), so a lot of volts with a very tiny current of a few microamps will surprise you and tingle but is not fatal. The Victorians thought that such stimulation was good for you and developed devices for "Galvanism".. using high frequency AC with a low current that gave you such a tingle and even electro-baths that were a bit more shocking. Still used in some countries. Then there is the dreaded ECT which is a different matter ....

I'm waiting for a Mod with built in Galvanic treatment electrodes.

Take a look at that breathing bite block, ain't science great?
