Resistance and Power

[Mr Ripple]

I think this is what I’m driving at - albeit poorly.

E.g.
View attachment 270165 View attachment 270166

I’d expect to see very little difference in vape between those two coils on a regulated mod.

You would see quite a difference.
Read my post above.
Halving the resistace as crispy suggests would take at least twice as long to heat up at the same wattage.

The heat capacity of the KA1 wire is 22.3 and the SS316L is 27.8. I thought you said it was the other way around.

I vape SS316L 0.41ohm at around 30W. 6 wrap 2.5id although 26AWG. At 15W it won't heat up.

I was going on this bit of Steam Engine:

Heat capacity
The higher the heat capacity, the slower your coil will be to heat up (and to cool down).

There isn’t a huge amount of difference between the values in the screenshots - would the resistance really have such a dramatic effect?

What may be confusing you is although both 6 wrap 27ga coils need 15 watts the higher resistance wire needs higher voltage, what it doesn't show is the one needing higher voltage needs lower Amps than the lower resistance coil (Amps x Volts = Watts) - so in reality they use the same power

Read my comment again.

I stated using SS316L instead of Kanthal would halve the resistance but have the same mass so would need the same amount of wattage. If you look at the two snaps from Steamengine that Simebaby posted you will see that this confirms it as the recommended power levels are similar even though there is a big difference in the resistance of the two coils. Resistance is only one aspect - the mass (total amount of metal) of the coil is just as relevant.

Something I’ve been meaning to ask for a while.
I vape purely MTL around 13-15W. The wire I use varies (though very rarely anything other than round wire), but certainly ohms can be anything from 0.5 to 1.
I use regulated mods only - so my understand was the resistance of the coil means very little, because whatever happens the power to the coil is 13W (or whatever).
However I’ve seen in numerous reviews etc people say that an atty performs much better with an mtl coil of 1ohm. So am I missing something. I get that there might be sutble differences between wire types but I would have thought 13W is 13W no matter the resistance of the coil.
Am I completely wrong?

I am trying to figure out what u are asking.

Yes on a regulated mod. 14 watts is 14 watts going to the coil, no matter what the resistance is, the mod will adjust the voltage to compensate.

Whether or not 14 watts is what u need to run a particular coil at is still the same ole start low and work your way up, pretty much every time
(I mean, u can get so it pretty consistent, but there is no 'perfect setting')

So do you mean that 7 wraps 2.5mm id of each kanthal and ss316l would both work the same with 12w of power?

I reread it and i still dont understand why vw an vv dont work the same, but they dont, lol

i was expecting a thread about politics.

It isn't long ago that resistances higher than 1.0ohm would have been seen as better for mtl vaping. What's better is whatever suits you.
