Beginner at dripping

[Darth Omerta]

Thats all fine, but Ohms Law is important to safety. My recommendation is not to just know how to plug in the numbers but to actually UNDERSTAND what Ohms Law and Watts Law mean and how they related to vaping. This is the entire reason why I still refer people to Baditudes blog. Nobody on this site or any other has given anywhere near as good an explanation of the concept and its importance to our safety and building abilities.

Everyone has pretty much hit all the marks...

I seldom go over 45-60W for my RDAs, I also Temp control a few of them, it's all in the build, a good dual coil build with 26gauge SS is just spiffy.

No need to go too low for the OHM range either.

Go with Claptons is you want a bit extra oomph..

The important thing is to have a good build, and good wicking done right, and to be on the watch for dry hits if you don't TC.

And don't flood your rda and end up with a messy leak. I prefer to have cotton in the bottom of the well to hold the liquid in.

I am a beginner at dripping I just want to know if 75w is a okay choice to make for dripping for being a beginner.

RDAs are my thing, properly built/wicked nothing else comes close to the flavor they produce. Personally, I prefer deep well RDAs that don't require constant dripping and or RDTAs which are basically RDAs with extra deep juice wells. What wattage and build is best for -you- depends on what you're after, cloudz, flavor or a compromise/combination of both and also what your vape style is, mouth-to-lung (MTL) or direct lung (DL) inhale. The build and power applied to it (wattage) also influence the intensity and temperature of the vapor produced. 75 watts would be fine for someone who inhales DL, is running low sub-ohm coils, likes a warm intense vape and has some experience with mods and attys. I inhale DL and prefer 0.4 to 0.5 ohm dual coil builds fired at around 45 watts, excellent flavor and vapor production.

Bad has his head on strait for sure. But there is far more to "thermodynamics" than ohms law.

I have always liked to use a car's engine as a simple example of how it works.
For proper combustion we look at AFR (air fuel ratio). The same is true of an atomizer, The air flow, and the liquid need to be balanced to the ideal AFR for proper taste, vapor, & throat hit.
Now think about temperature, Combustion heats the car's engine, but it's the cooling system that keeps it at the proper temperature. If the fan fails or the radiator runs dry the engine will overheat. An atomizer works the same way. Power heats the coil, but it's the airflow and the liquid that keeps the coil at the desired temperature. (and if TC kicks in, it simply means that the airflow or liquid is insufficient for the set power level)

The way I vape is pretty much immaterial for what anyone else would want, but this is what I do.
I prefer a cool MTL vape with lots of flavor, which is pretty easy to accomplish.
I mostly use a single battery mechanical mod (Caravela), and I build for the batteries "plateau" voltage. (3.7-3.6v for most quality batteries) This means a 1.8 ohm coil with my choice of RDAs. (A7) This equates to a ~2 amp draw @ 7-8 watts. (ya think I'm safe using 20 amp batteries)

Point being that it's easy to stay within safe limits when dripping if you choose to do so.
However it's up to you to keep the coil wet when dripping, the atomizer will not do it for you. It is also up to you to stay withing the batteries CDR limits when using a mechanical mod, the mod will not do it for you.

add:
I have always liked to use the 50% of a batteries CDR rule. The reason for this is that as a battery ages it's mAh degrades, and as the mAh degrades so does it's CDR. This means that several months down the road a 20 amp battery may only be a ~10 amp battery. So for a 20 amp battery a 0.4 ohm (10 amps) coil would be as low as I would want to go.

I will be getting the sigelei 150w temp control box mod and a royal hunter rda by counil of vapor to me I think that would be a good setup for me at the time being.

I just reread this thread and noticed that my favorite 2 blogs to mention have gone unmentioned.

@Jennifer Dobbs
If you really want to start building coils for either a mech or a regulated mod please make sure you read through the following blogs:
Mooch's blog | E-Cigarette Forum
(18) Baditude's Blogs | E-Cigarette Forum

Mooch is the battery king! Detailed information on battery safety, selection, maintenance are all available on his blog. Baditude gives arguably the best explanations for Ohms Law, building for beginners, and most importantly safety.

I have a 0.21 build, 22G 6 wraps kanthal 3mm inside diameter dual. I run this on average to about 80 watts. Last night I pushed it up to 90. Therefore I am familiar with my build. But on this build would you push it over 90 watts being that it's a low build?

Im not sure what you mean by "therefore I am familiar with my build". Running your build at a higher wattage does not equate to having a better understanding of your build.

What I will say is that the optimal wattage is not based on the resistance of the build, rather it is based on the mass of the coil. Heavy, thicker guages wire tends to have a lower resistance and requires more power to heat up. This is due to the flow of electrons through the medium(the wire). Think of drinking water through a straw. Water represents the electrons(or power), and the straw represents the wire. If you have a very wide straw then there is less resistance and more water comes through than if you had a very thin straw.

A dual coil build using 22AWG and running at .21 ohms would reach its optimal heat flux at around 72W, whereas a dual coil build using 28AWG and running at the same resistance(.21ohms) would reach its optimal heat flux at around 9W.

The optimal wattage to run your build at depends on the mass of the coil, not its resistance.

And all this time I thought you were just here for popcorn and beer

Well I do enjoy the popcorn and beer very much...just trust me when I say dont vape either!

I didn't read every reply but here's my advice. Build a coil(s) that read in the .4 or .5 range to start. These slightly higher ohm coils will give you a good vape and should be well within the range of your mod. Coils at these .4+ will allow for a good vape at less wattage so a 200W device is not something you need to run out and get. Safety is the key and understanding is very important. Take some time and either research safe coil building or as someone in a local shop to help. Most shops usually have guys that live to help others but get the opinions of 2 or 3 people.
