Hi Ohm v. Low Ohm

[dherrington]

I am sure someone out there can answer this question. What is the advantage (or disadvantage) of using a coil with a higher ohm rating on something like a Kanger Protank? You can get them in 1.5 I believe right up to 2.5. When would you want to use each?

Thanks in advance.

It really comes down to preference and device.

I tried a protank on a Ego-T (18650 mod) and I had to use a 1.8ohm to get it to perform satisfactorily considering it was a 3.6V or ~4V output device. I was used to a Tesla (VV/VW) with a AGA-T2, so my standards are kind of high.

higher ohm ur battery will last longer. the protank is a bottom coil so even the low ohm will not produce a warm vape. i dont like them for that reason.

Hi

What battery devices will you be using it on?

 

[BobInSD]

Since I mainly vape with Vamo set to watts, I rarely even need to check ohms. Just dial in the right wattage for the juice, and I'm off...

 

[CrimsonJack]

I've been wondering the same myself. I'm using Protanks on an MVP.

Too bad we're not talking about RBAs where it's more applicable. Watts do matter. I'd love to see you get a vape on 0W. As far as these commecial coils go, power throughput essentially determines wire temperature with a nearly linear relationship up to a point.

Do you realize how advanced that thread is in relation to the OP's question? That's like me asking if I should set my toaster to light or dark and you post a link to a thread about thermodynamics without any context.

That is actually only true in a time-temperature series, and the point at which it stops being a linear relationship is the operating temperature of the atomizer. So actually that statement isn't that useful. Replacing "wire temperature" with "vapor production" might be closer to helpful.

While it is true that varying the coil length but not gauge will have this effect, not all commercially available atomizers work this way. I have gotten some kanger compatible heads that actually have thicker wire in the lower resistance heads.

Tio estas vere nur la veron en tempo-temperaturo serio, kaj la punkto je kiu ĝi ĉesas esti lineara interrilato estas la mastruma temperaturo de la atomizer. Do fakte tiu aserto ne estas tiom utila. Anstataŭante "drato temperaturo" kun "vaporo produktado" povus esti pli proksima al helpema.

Kvankam estas vero ke varianta la bobeno longo sed ne kalibraj havos tiun efekton, ne ĉiuj komerce havebla atomizers labori tiamaniere. Mi akiris kelkajn kanger kongrua kapoj kiuj fakte havas pli dika drato en la malsupra rezisto kapoj.

You know, I walked away to get something to drink, and this thought occurred, given that the wicking is able to supply juice to the region for atomization. What I really meant to say, though I agree it isn't quite relevant to this thread, is that the relationship of temperature vs power is rather linear with a short dt.

Surprising. I've only really gotten ones with more wire vs thicker wire. VMMV I guess.

Back to selecting Protank heads, what battery device are you planning on using it with?

In the 1.7-2.x range yes I think it is most common to see more wire. But I'm pretty sure for 3.x range the wire size comes down on many atomizers.

The reason I posted the link, is that by post #5 in this thread, the topic was diverging in this direction.

My point was that the gauge of the wire is relevant, along the ohm rating. There's another similar thread (somewhere...) where VW users complain that using a different coil, gives a burnt taste, even though they use the same wattage setting.

If I addressed the first post only, where there's no reference to a VW, the answer would be different: a higher ohm gives you a lower temperature, with more or less flavor, depending on what e-liquid one is vaping.

I think a safe answer is "it may work differently"!

So the higher the ohms which is resistance the higher voltage needed.
So silly question, which produces more vapor higher or lowr ohms.
Or is that dependent upon the wicks u use?

Diverging again: We need a wiki for this stuff.

Lol sorry O
