Do ohms matter?

[kenflawless89]

i was just wondering if i built a coil does it matter what the oohms are? if im gonna pick it on a mechanican mods.. im picking it on a trident tripping addy .. i know it matter if im running a battery that runs off of vareible voltige.. im brand new at this so anything helps.. or can someone explain to me and make it as simple as possible

Ohms matter because the lower the resistance (lower ohms) the warmer the vape will be. On a mechanical mod, you can vape a much broader spectrum of ohms.....you can go much lower, for instance, than you can on a VV or VW mod because there's nothing to cut it off. But ohms matter a lot in the quality of the vape. They will also affect the amount of power that is required of your battery. If you're using a 3.7 volt battery, then if you like a warm vape, you might shoot for a 1.5 ohm atomizer or cartomizer or rba coil (or even lower)...but if you like a cooler vape, you might like a 2.5 ohm atomizer or coil.

The voltage of your battery doubled, divided by the ohms of your atty or coil equals the wattage (output power) of your device, basically. So once you figure out what you like, you can sorta dial it in by changing the ohms of your atomizer/coil.

Trying to keep it very basic here.....but that's why ohms matter. Does that make sense?

Please read the info in the rebuilding subforum and watch a ton of videos on rebuilding before proceeding.

Ohms matter a great deal and not knowing what you're doing with respect to resistance and rebuildables can result in very, very bad things happening.

Just looking out for ya, buddy.

Sure it matters, the lower the resistance(ohms) the quicker it will heat up and the warmer it will get as compared to a higher ohm coil. It matters more with a mechanical mod than it does with VVorVW, because you can adjust them.

Ok. Looks like I'll be doing a lot more research before I do anything crazy. What I'm aiming for is sorta a cool vape. But most, I wanna produce a BIG cloud. I've been watchin rip trippers videos on YouTube but he makes it look so easy. I wanna put the duel micro coils in my trident, but then again I don't know what I'm doing. I just got my kathal wire 28 gauge and I got organic cotton for wick. I just orderd the vamo v3 for reading my ohms.. my set up that I wanna build the coils for is a private v2(clone)with 18650 battery and a trident rda(clone).. what JC Okie says makes sense .. but somehow I keep confusing my self. Haha.

My bad one more question.. so if I read my ohms, and say they are like at 2.5 ohms. And if I wantted to go lower.. or higher in ohms would I do more wraps or less wraps to get lower ohms?. Right now the coils I got in my igo-w have 3 wraps and it blows pretty nice clouds but I'm looking for more vape/Big. clouds..

Dang it I forgot to quote you.. can you read both my replay and tell me what you think?

Ok so. When it heats up and gets warm. I will feel it pretty rough in my throat.. correct?. And to get rid of that I would have to run a higher ohms.? Lol my bad for all the dumb question..

Less wire equals less ohms. Yes, more ohms would be cooler and less throat hit.

Does 1 or 2 less wraps make a big differance in ohms?

i mean no disrespect, but your questions indicate that you really, really need to read up more about coils, ohm's law, and in, particular, battery safety.

you should start with battery safety. read the ones about battery safety here for a good start: E-Cigarette Forum - Baditude - Blogs

if you are now at only 3 wraps and you want to try for even bigger clouds, you are already in a danger zone unless you learn this stuff.

it really won't take long to read about batteries and coils and your face will thank you.

 

[NealBJr]

one last variable that hasn't been mentioned... what battery are you using and what's the maximum amp rating for that battery.. that's a safety issue there if you don't know. (by safety, I mean a battery exploding if it's a cheap one).

I reccommend watching tonnes of videos on how to do it and do your research.

Big clouds and heat go hand in hand. The more clouds you make, the hotter the vape.

This also goes hand in hand with less ohms...the less your ohms (fewer wraps with same gauge wire) the hotter your vape, the bigger the clouds.

You should stay with higher ohms till you get some more knowledge, and experience. Remember you are doing this at your own risk, and it can be dangerous and can cause injury to yourself. The questions you are asking should be answered before you start.

 

[kenflawless89]

Yeah no disrespect takin.. I honestly know absolutely nothing about building coils... I just recently got it in my head to build coils.. thanks a lot for the link.. It didn't cross my mind that my battery would be in any danger..

I am using a pink Samsung 3.7 18650 battery the mah is 2600.. I got it from the local vape store for 20 bucks(yeah I know I got ripped off).. but I just orderd the efest 18650 2000mah.. they should be here tomarro. My pink Samsung dies like in half a day of vaping..

If you're using the same wire.. more surface area=more heat distribution, slower it will heat up.

Wattage is a simple way to look at heat production with vaping.

I hope you like math. Here's the vaping bible

I recommend that you find out the Max discharge rating of the battery you're getting. For example, I have the Red Efest 18650 2000mah and that is rated at 10 amps. To give yourself a bit of a safety margin, it's recommended that you limit your coil build to 80% of your battery's max discharge rate which in the case of the Efest is 8 amps.

Knowing the maximum safe current or Intensity (I) = 8 amps
Your battery's voltage (V) at full charge = 4.2 v

Then we can find out the ohms or resistance (R) = V / I
4.2v / 8 amps = .5 ohms

With your efest batt, you'll know you're on the safer side as long as you keep it above .5 ohms.

not sure if either of those is "safe". you need to look up the C rating of the particular battery, then use ohm's law to see if it will be safe.

mah is a secondary rating for this application. it only tells you how long the battery may last. the C rating will tell you how much power it can deliver over a short period of time which is more important for safe vaping.

Here's some info on your Pink Samsung. Please check if it's got the same part number. It's only rated at 5200 mah or 5.2 Amps. I (personally) would not use this type of battery for vaping... that's just me though
