No Resistance wire?

[iamtumus]

Unless you have a superconductor you have some resistance. This is just electric 101 stuff and is fairly irrelevant to e-cig discussion.
A more accurate description is low resistance vs. high(er) resistance wire. Resistance is just a measure of how readily the electrons flow across the medium and which is generally predictable by medium material and size. Bigger medium will typically produce lower resistance materials being the same. Silver is a very good conductor of electricity and as such, for the purposes of e-cigs, is "non-resistant".

no. nr wire is wire that puts out no watts because it has no resistance and you can't divide by zero.
so it is wire that don't heat up.

VAPOR SCIENCE

Here I used approximately 1 inch of 30 AWG 999 silver wire & used an ohm meter & ac7 to do the testing.

Here is approximately 1 inch 32 AWG pure nickle.

I must note that the ac7 is stainless steel & adds some resistance. The pure nickle should be @ nearer .08 per inch, so I deduce the internal resistance of the ac7 to be near .04, thus the silver wire is likely about .04 in reality.

*32 AWG pure nickle specs: Resistance- 0.95 ohm/ft

(FYI: Larger wire diameter does not increase resistance.)

Oops, my bad. That was a typo.

I am thinking about using the Nickel non-resistance wire for the positive lead of the next genesis build I do. Every time I screw the cap back on/off the DID it seems to slightly spin the center post and causing my reading to change...sometimes dramatically...to the point I have to readjust everything. I am hoping this will be fixed with a non resistant lead.

BTW people generally call very low resistant wire...non resistant or zero resistance wire.

Exactly, just like absinthe with a thujone level of 10ppm or less is considered thujone free... (it has been proven that all the best brands from the turn of the century are in fact, thujone free, which is good news to absintheurs everywhere, as it means that traditional absinthe is now widely available in both EU and North America... )

But i digress...

Another good comparison would be the misconception that decaffeinated coffee is caffeine-free... when it isn't.

I agree, but thats not my point. 0 resistance is 0 resistance. They guy shouldn't be marketing it as 0 res because there is no such thing.
Its akin to false advertising. Besides that, 0 res wire wouldn't work in a atty. He is just trying to lure stupid people in who know nothing about electricity.(No offence to the OP, who, by using logic figured that the lower the res the better the wire)

Of course a 1/16 inch wire .1 nanometer thick is going to have damn near close to 0 res. But that wasn't my point. Res is res no matter how small.

It is sold as no-res wire to differentiate it from the res wire used for the coils. I don't believe anyone is misleading anyone when it comes to this application. Is there resistance? Yes. It is next to nothing, however, compared to the resistance of the Kanthal/NiChrome wire. "No-res" wire is used for the legs of the coils for VN and T3s and such where you have wire passing through a grommet of some sort. You do NOT want that wire heating up and melting the grommet...your vape WILL taste like ....

"Resistance" wire for coil = good vape. Resistance wire for legs of coil in the above devices = ....

Dude, it's a marketing name it's not a marketing scam or lie. It's called no resistance wire to distinguish it from common copper wire and others of higher resistance. It's a name, not a CofA claim.

There is some truth to the claim that all wires carry some level of resistance...

Just like there is some truth to the claim that apple seeds are poisonous...

Resistance wire (Nichrome, Kanthal, et al...) shows high resistance over a very short length... It is purpose built with electric heating coils in mind.

"Non-Resistance" wire, while it does have resistance, would take an extremely lengthy piece of wire to equal the same amount resistanc efound in that short length of Kanthal. And in the quantities used in our applications building atomizer coils, the amount of resistance is beyond the measurable yield of my Fluke multimeter... It reads... 0.00 Ohms... So sure, it probably has something like .000009 Ohms of resistance... In the world of vaping, that's No Resistance... Heck, in the world of my fluke meter (Which I trust with my life...) that equals No Resistance...

So relax...

Apple seeds are poisonous... If you have like a thousand pounds of them!
