RDA Higher Ohms, Higher Volts, Higher Watts = More Battery?

[Roiikka-Ta]

I'm a little confused here.

I've been vaping on 26 gauge, 10 wraps, 3mm diameter, dual coils, kanthal in my IGO W3 RDA and a IStick Pico I just bought.
I read a little bit just now of a few different sites and decided to try out the same exact setup but with 28 gauge kanthal.
What I was looking for happened. More battery life.
What I'm confused about is, is that how can all of these things have increased (that I stated in the title) and yet I get MORE battery life?
Same hit length too, as well. No shorter hits. Nothing.
Am I missing something .. ?

My knowledge is, is that the lower the ohms, the harder it's going to hit. As in, the ohms versus wire gauge are a slight way of saying "the lower you go in ohms with the same setup, the more power you are going to need but it's going to heat up faster".

Is that a slightly incorrect statement?

I think i just answered my own question, but could somebody please verify?

I always thought the lower ohms/lower gauge wire versus the higher ohms/higher gauge wire were pretty similar.

Does this just revolve around the fact that "thinner wire heats up quicker with less electricity" and people just want thicker wire and higher "drain" batteries so they can get shorter "hotter" hits than slower, cooler, more efficient rolling drags off the RDAs ?


Ultimately my confusion:
Cuz I use less watts now with this higher gauge wire but then I ramp up the watts to what it was before with the thicker wire and I don't get all this spitting and heat ..

Weird ?

With thinner wire the surface area of the coils is less, so it will result in a higher heat flux...You will need less wattage to get same temperature as with thicker wires.

I read and got this yesterday "Understanding the relationship between power and coil resistance" in sonicbomb's blog has sonicbomb in this forum, sorry I could not give a direct link because I am new to this forum. This hopefully can help you, as me and thank you so much to sonicbomb for his efforts to explain this.

Thank you Nasar!

With thinner wire the surface area of the coils is less, so it will result in a higher heat flux...You will need less wattage to get same temperature as with thicker wires.

But why do all my settings go up (higher) when I move the same setup to a 28 gauge from a 26 gauge ? Including watts.
And it's a cooler vape, too. Is it just the way the coils ramping up is reacting with the vape juice differently? That's also what's causing my confusion is the vape is cooler now.

It's cooler on my single coil RTA , also, with about the same ratio scaled down into a single coil. I just use this RDA because the cold climate I'm in at the time makes the juice wick too slow in my 3 tanks ..

 

[Verb]

The main variable change that is causing the observed results is reduced coil mass. You're on a regulated device; so, resistance has almost no effect. Temperature of the vape entering your mouth depends on juice composition, chamber size, power, mass, surface area, wicking, and air flow.

No, more resistance = higher ohm, not lower!

 

[Roiikka-Ta]

Verb!

lol sorry i just had to haha ..

Ok so I'm guessing it's just that small tiny little ratio I'm going to focus on in between the higher and lower output and the lower and higher ohms.
It really does help to be able to put it all into one really quickly. I feel bad for some of the noobs out there that got to calculate everything out .. I'm guessing this is just another stepping stone of the learning process.

What Verb said; basically the more juice the hotter the vape will be all in all and the smaller the coils the cooler it will be as per the juice make-up.

That's weird. Ok so in a way, the thicker the "resistance wire" (kanthal) the more resistance there is. Because it's resistance wire. THAT makes sense now. Now I see why the higher volts are needed. Because it's all "collecting" in the coil NOT passing straight all the way through it. And the higher volts let it "push" or "squeeze" or "travel" through the thinner wire better. Which in return heats up the smaller wire faster because it can take less and the larger wire slower because it can take more. And that's why it heats up from the middle. And that's why it's coil shaped. Because it's like a power reservoir. ^ _ ^ .. Did I get that right .. now .. ? LOL

 

[frjaldomr]

No, more resistance = higher ohm, not lower!

You know, you're right. Maybe I don't know what the heck I'm talking about here...

LMFAO .. frjaldomr it's ok. We all knew what you meant.

It is simple, thicker wire takes more current (amps) to heat up where a thinner wire will take less.

More current, lower battery life
Less current, longer battery life

 

[daviedog]

26awg = thicker ,less resistance/cm.
28awg = thinner, more resitance/cm.

It's about Mass & Heatflux, what you are perceiving.
Go to Steam engine & download for a thorough understanding of what's happening..

Thicker wire = larger coil = lower resistance
Longer wire (more wraps etc.) = larger coil = HIGHER resistance
You can't just go by the ohms.
By "larger" I mean more surface area, can handle more power. It's possible the first build was too much for your tastes, atty, airflow, settings. So the slightly smaller coil (28 ga.) just works better for you. If the larger one had been more optimum, you might have to reduce power with the smaller one, but you haven't found where the coil is the limiting factor yet, evidently.

Thinner wire, being less heavy compared to its surface area, does heat up faster *all else equal* but in this case it's not equal, so that makes a bigger difference (in this case, it heats up even faster because it's in all ways smaller).
