Why super-low resistance

[serenity21899]

I understand the basic resistance levels and understand how to adjust volts to match and all that good stuff. My question is more about the quest for super low resistance when building coils, say under 1.5ohms. What advantage does having a resistance of 1.2 or lower have on one's vaping experience? I missed that day of vape school apparently. Thanks.

Personally, I don't even like 1.8. Everything tastes burnt to me, even at low voltage.

 

[serenity21899]

For the most part, neither do I. Kinda why I was asking about it.

You got me. I like my LR, but that's as in 2.0.

Even coils below 1.0ohm does not taste burnt when done right. But you have to hit a good balance between a wick that wicks fast and a coil that is nice and even. If you're doing a genesis atty and it tastes burnt, you're doing it wrong.
Also, a sub 1ohm vape doesn't necessarily vape super hot as you might think, as genesis atties are faily large and the vapor have a little time to cool off before it hits your throat.

I'm running a 1.2 omh coil on my ihy, and I found that I only would get a burnt taste if the wick is too thick or too tight. Also, if your talking about Genesis style tanks like the DID, try try taking the screw out of your fill hole, it helps the wicking process and reduces dry hits while running a hot coil.
Yet another trick is to roll a wick which is hollow, this will greatly improve the flow of juice.

The people that do the high-wattage vaping are using 28 gauge wire. It's a lot thicker wire, so higher wattage running through it doesn't get nearly as hot as thinner wire. Also with the fast wicking of RBAs, the wire stays wet. If you tried anything in the 15+ watt range with normal atties the coil dries quick which causes it to really heat up, burning things or causing a dry hit. A properly set up SLR coil acts a lot differently than a regular set-up when using high watts.

Without getting technical with omh law Running a lower coil, on a Mechanical device gives you the feeling like your vaping of a freshly charged battery without really noticing the voltage drop. Meaning you get the same flavor and vapor production for a longer period of time. ( less coil the faster it heats up) how low you go its up to you just be safe about it.

Spot on Jerms.

I stick to 1.5-2.0 ohms with my dripping atty. My experience is it seems to produce vapor faster than a 3+ ohm coil, regardless of volts/watts.

Coil design, not simply resistance, dominates how a coil performs at a given voltage.

With genesis style devices you can generally run higher power than you would with normal heads without burning juice.

The main reason people are using extremely low resistance coils is because they are using mechanical PVs. With a variable voltage or wattage device you can increase the voltage when running a higher resistance coil. With a completely mechanical device you are running at straight battery voltage, which is nominally 3.7v.

In order to increase the power you have to reduce the resistance of the coil by either using thicker wire and/or less coil wraps. And seeing as genesis style attys can use more power without burning sub ohm coils are not uncommon.

Thenk you for the info everyone, I have yet to get a rebuildable atty, but I have a Reo on the way, so I have been looking into it. Just was kinda wanting to know what low resistance actually did since I really don't do it.

So, here's a vivi nova coil at about 1.8 ohms beside a 0.7 ohm coil with 10.5 square inches of rolled stainless steel mesh behind it. You can put a lot more energy into that before it gets a burnt taste. (about 25.2 watts, actually) It's all about proportion.

I tried 1.5 ohm cartos, didn't like 'em. I prefer 1.8 ohm to 2.4 ohm. Vaping at 3.3V to 3.8V. But I haven't tried anything higher than 2.7 ohm or higher than 4.2V.

i get nervous sometimes as my switch gets too hot. But awesome taste and vapor!

wrong thread ... sorry!
