Ohms of coils Vs Battery Drain Vs Vapor production

[Vapingmonkey]

Hopefully a quick one, just wanted to clear up something

Have I got this right

Lower ohms = hotter coil faster , faster vape production, Faster battery drain, hotter vape

Higher ohms = slower coil heat, delayed vape production, longer battery drain

Basically I like long, deep lung inhales, sometimes taking 2-3 long tuggs before exhaling and have been building at 2.4ohms using .20 Kanthal which is fantastic on my protanks

When I use my RSST or T2 the battery drain is really quick, i'm wondering if this is because I am at too high an ohm level or have too many coils

I'm not sure If I have this backwards?

If anyone could help me fill in the gaps it would be appreciated, my common builds are:

.20 Kanthal @ 6 Wraps on 2.5mm drill bit = 2.4ohms (Preferred)
.20 Kanthal @ 5 Wraps on 2.5mm drill bit = 1.8ohms

Would .32 Kanthal or .9 ribbon make any difference to the drain / vapor production?

the only difference made would be the ohms genereally though obviously more coils means more surface area getting heated so more liquid vapourized but tbh the difference between say a 4 coil wrap and a 8 coil or 15 coil microwrap is going to be insignificant compared to the difference between a mush hotter lower ohm coil over a higher ohm coil.
.32 kanthal equals thicker wire so less wraps = higher ohms over thinner wire but you get more srface coverage cos its thicker.
perosnally i perfer .28-.32 wire in an 8- 10 wrap micro coil. give me a large surface area, heats up quick and comes in around 1.7 ohms on my kfl, plenty of flavour, plenty of clouds and im not burning a ton of juice

What's confusing me is in my Protanks I use .20 Kanthal which is thinner than my .32 wire, yet everyone says .32 is thinner

surely 200 microns (.20) is smaller than 320 Microns (.32)?

I'm getting
1.4ohms with 7 wraps of .32 giving me slow heatup and minimal clouds
2.4ohms with 6 wraps of .20 giving quick heatup and plenty of clouds

I would have thought with less resistance the heatup would be quicker as it takes less effort for the current to pass through the wire, and with a thicker wire the current can pass through quicker

So by that reckoning 1.4 ohms on a thicker wire should beat 2.4 on a thinner??

People may be referring to wire using the American Wire Gauge (AWG) system where the lower the AWG number, the thicker the wire. Check wikipedia for some info Confuses the hell out of me!

But your two coils make sense to me, 0.32mm wire is thicker so lower resistance, 0.20mm wire is thinner so higher resistance.

Ahhhhhhh that makes sense, no wonder I got confused, trust america eh

Ok so with that cleared up and knowing i'm not going mad, Should my .32 at 1.4ohms be heating up alot quicker than my .20 at 2.4 ohms.

common mistake, i always refer to kanthal in mm rather than AWG ( add to the fact AWG can cover 2-3 thicknesses of wire )

ok so just to confuse things

.9 Kanthal Ribbon . . . . . . . is that 0.9 ohms per inch? if so the coil would have to be huge to get 1.8 ohms

I think the short answer is that a lower ohm coil produces more vapour than a higher one.

The long answer I believe is a little more complicated (and I'm by no means an expert, or clear on it all myself!). A thicker wire has less resistance and therefore dissipates more power, but it has a larger cross-sectional area so there is more metal to heat, but it has a larger circumference and therefore contacts more juice than a thinner wire. I myself jump to the conclusion that thicker wire is hotter or heats up quicker than thinner wire, but temperature alone may not define a coils vaping ability: I imagine it is a combination of temperature and the area of wire that touches the juice.

As above. A thicker wire takes longer to heat up than a thinner wire. Low ohms draw more power than high ohms.

0.9 I believe is the ribbons width in mm.

Generally speaking, a coils resistance depends on the material the coil is made from, it's cross sectional area, and its length.

The 0.9mm ribbon you are considering should have one other dimension to give its cross-section (wire is circular therefore is specified with just diameter, whereas ribbon is rectangular and therefore should have two dimensions to define it).
