Resistance?

[KRaysDaddy]

Alright, I feel like an idiot asking this, but I'm about to attempt my first rebuild, and I know that resistance is based on the amount of coils. More coils means more resistance, and vise versa. The issue I can't seem to find an answer to, is which makes more vapor, high, or low?

I'm using a Smokless Image 900 mah with a T3, not that that's relevant.

Thanks in advance.

congrats on quitting cigarettes. what gauge kanthal are you using?

it's kinda confusing because there are so many variables involved. you can go with a thicker wire with less wraps or smaller wire with more wraps and still come out with similar ohm readings. but technically, more wraps equals more surface area vaporizing the liquid which equates to more vapor production.

Sorry, it's 32 gauge. So higher resistance makes more vapor? That makes sense because that would mean more coils, but I thought lower resistance would mean it would heat up quicker, thus making more vapor... I guess trial and error is gonna be the true test.

I = V / R
P = I × V
P = V² / R

Lower resistance means higher power. Result: more vapor.

Vapor production is increased by making a hotter coil and then getting more airflow past that coil. So if your going to do a lower resistance coil then also do an airflow mod to your T3 also. But don't go to crazy with the coil, as your ego has a lower amp limit.

Link to this i have the same deal as op dont mean to thread jack.

A wrench in one hand and my PV in the other.

Actually length of wire is directly proportional to resistance, so when you wrap more coils you effectively get a longer length of wire which results in higher resistance. If you read the specs for your wire you will see it has a resistance/length value. You use that value to calculate accurately how much resistance you have for your specific length of wire.

100 ft Nichrome 32 AWG
Resistance- 10.57 ohm/ft

1 inch of this wire would then produce the following resistance:

[10.57 OHM/FT] x [1 FT/12 INCHES] x [1 INCH] = 0.88 OHMS

OR

RESISTANCE = 0.88 ohms/inch

The more surface area you can heat the more vapor you will produce. That's why ribbon wire and micro coils are so popular now. Now with 32 awg you will end up with a high ohm coil that, if you can heat properly, will do well. With 28 awg, same number of wraps will end up lower ohm, with the proper heat it should produce more since there is more space to cook on.
You need the proper airflow, don't forget. .
Look into micro coils, they are easy ( for me I have trouble wrapping on a wick only)
