OMG!! Or, Ohm My God!!! [help w/ohms plz... oh, and, hello!]

[TalkingCactus]

I think I said it all in the title.... I need help w/ohms.

So, this carto I'm ordering comes in 2.4-2.6 and 2.6-2.8 ohms. Awesome! Right? Not for me, I don't know the difference, yet. So I'm ordering one 5-pack of each ohm range of these new top coil Phoenix cartos from Got Vapes GotVapes PHOENiX™ : GotVapes.com, E-cigarette Supplies - Atomizers Cartomizers Mods Juice and more and I'm fine w/learning this way. I'm more of a "hands on learner".

Why ask then, you might ask. It could get expensive ordering all ohm choices every time I order something. Period.

Batts I have at home are all joyetech: 6 X 510-T> 2 manual and 4 auto. 4 X Ego-C> 2 650mAh Twists & 2 1,000mAh Upgrade 2's.

Oh yah... Hi group! My name is Matt, and I'm a smoke-a-holic.

 

[moishesmom]

Hi Matt - With my very, very small amt. of knowledge I would use the 1000mah w/what you ordered. The lower the ohms such as a 1.7...the more battery power is needed + the more drain on the batt - therefore - your going to be recharging more often. This reply stands to be corrected, please feel free. Good luck to you Matt - welcome & enjoy!!!

edit....you can also use your 650's - but try your 1000 first.

 

[MickeyRat]

In general, the lower the ohms, the hotter the vape and the faster they will drain your batteries. The ratings you mentioned aren't that far apart. I'm not sure you'll see a lot of difference.

 

[Vchick]

The 510 style will fit either battery, the ego style won't work with the 510 battery (slim batt) hth!

 

[bruiser]

Since you didn't order any low resistance stuff, they should work with all of the batteries. Since you have some 650 and larger batts, you might think think about some LR cartos.

 

[sailorman]

All of your batteries accept 510 cartos/clearos, so they all will fit.
Nothing you've selected is particularly low resistance. So none of them will hurt any of your batteries.
Rule of thumb is to stay at 2ohms or above if your battery is less than 450mah.
All of those clearos are above 2ohms, so you can use any of those batteries.

As the Rat explained, lower resistance(ohms) gives a warmer vapor. Higher ohms gives a cooler vapor.
For the future, remember this simple formula to decide what resistance (ohms) you want to get.

Volts x Volts / ohms = Watts.

Watts = heat. Most people prefer somewhere between 6-10 watts, depending on the juice. Heavy, dark juice, like tobacco works well with higher watts (more heat). Lighter juice, like fruit flavors, get washed out or burnt tasting at high watts.

Your Joye 510s are 3.7V. Your eGo types are 3.4V.

Plug those voltages in to that formula and you can see the what effect each of those resistances will have on the watts (heat). You will see that the lower the resistance and the higher the voltage, the more heat (watts) will be used to produce your vapor.

The lower ohms cartos should work best with the lower voltage of the eGos. They both should work better with the higher voltage of the 510s.

 

[chagrin]

Volts x Volts / ohms = Watts.

Can you explain this ? Are you multiplying the 3.7v of the battery by itself ?

 

[sailorman]

BTW, I'd skip the 2.6-2.8ohms. They won't work well on the eGos, except the Twist when you turn it up over 4V. The 2.4-2.6 will work better on all of your batteries. The difference won't be huge, but if you get some 2.8s, they will definitely be noticeable when compared with 2.4s. If I were you, I'd order the 2.4-2.6 and hope they turned out to be on the low side of that range.

 

[sailorman]

Can you explain this ? Are you multiplying the 3.7v of the battery by itself ?

Yes. If the battery is 3.7V, and you have a 2.4ohm carto, you end up with 3.7 x 3.7 / 2.4 = 5.7 Watts.

I wouldn't use anything over 2ohms with a 3.4V ego. 1.7ohms is ideal, as it will produce 6.8 Watts without too much strain on the battery.

Interesting...very interesting, i too have been wondering about this. As "Matt0111" said "i'm a hands on learner" too. I took electrical engineering at ITT (dropped out) and have been wondering about the ohm/resistance thing. From what i do remember learning the taught us that the less the ohm/resistance the less power needed. Again.....thanks to this forum i'm learing alot!!!!! Anyway good questiong Matt0111, i've been wondering the same, thanks guys/gals!

 

[apbtdog1]

Yes. If the battery is 3.7V, and you have a 2.4ohm carto, you end up with 3.7 x 3.7 / 2.4 = 5.7 Watts.

I wouldn't use anything over 2ohms with a 3.4V ego. 1.7ohms is ideal, as it will produce 6.8 Watts without too much strain on the battery.

this forumula? I don't understand.....!? If a "Vaper" has a 3.7v battery and a 1.5ohm carto then....? 3.7 x 3.7 devided by 1.5ohm = 9.12 Watts? is that right? So that means a lot of Watts......so that means..... A LOT of strain on the battery, right?

 

[Stosh]

You did just fine with your order, one pack of each and try both to see what you like best. All for the cost of less than 2 days cigs from when I was smoking... Experimenting with different attys, cartos, and dreaded ohms is great so long as it's one or two at a time.

Starting out I was very hard on my equipment, two packs of cartos didn't last very long...
Now when something new is released, I still want to try one, they just last longer.....

 

[Stosh]

Here's an easy calculator Ohm's Law / Watt's Law Calculator just plug in the numbers...

 

[Andy Thatcher]

Do a Google for Ohm's Calculator.

Put in the voltage tour battery pushes out, put in the resistance of the carto.

This will give you the watts you are vaping at.

Most prefer between 8 and 10 watts. I would suggest that for your Ego's you want below 2 ohms. 510's between 1.5 up to 2.4. Twists at 4.8 between 2 and 3 ohms.

Taste is subjective and some prefer a warmer vape than others you will have to play and learn your preferences.

Keep it easy for yourself. You have around 3.5 volt batteries. For hotter vapour start around 2 ohms and up to around 3 ohm for more mellow vape. So what you have is good for the most part.

Heya, I've attached a spreadsheet tool that I created for myself while trying to figure out low/standard/high resistance attys/cartos as well as if I wanted to get into variable voltage or not.

As one of the previous posters linked, you can just use a ohm's law/watt's law calculator...but I wanted a visual reference on the correlation between volts/ohms/watts and amps and couldn't find a tool...so I made one. Maybe you and/or other ECF newcomers might find it useful.

DISCLAIMER: This is simply a spreadsheet...I take no responsibility if someone blows their head up...use at your own discretion & risk. Also, all the numbers and equations are solid...but some people may not like the color thresholds. I was going off of what I consider "average" likes and dislikes. I know some people are perfectly happy with a 4watt vape and may not like that it falls into the gray zone. Other people like to suck on the end of a hairdryer and won't like that 12watts is in the red zone. Whatever...if you're familiar with excel, then you can just go in and edit the conditional formatting on the cells to set the color thresholds to whatever you like. Personally, I find that staying in the dark green band as close to the 1.5amp line as possible is a good mix of vape quality and hardware longevity. (I'm think I'm pretty average in liking around an 8watt vape.)

I was beginning to wonder if anyone "got" my question. Thank you Sailorman!

apbtdog1 - you're welcome I just had to know WTF all this ohm stuff was, so I asked.

Ive lurked here for quite a while, read A LOT! So, I finally signed up last week, and read some more! I've almost read the entire FAQ thread, and all of the threads it links to. In all my reading I've learned a lot, but never once did I come across a good explanation like SailorMan gave. Temperature of vapor, strain on bats, etc. good stuff Mang!

BTW: since I'm new, here anyways, I'm using this as a "Hello" thread too, so I think you should know my screen name will soon be TalkingCactus. So in the future when you see a TalkingCactus, just know it's me, Matt! I tend to lurk more than comment, but you'll see me from time to time. I'm definitely the type to read the thread creation post and ALL comments (something i wish a few others did as well) before commenting. So even tho I tend to ramble, don't be afraid to read my comments, just because it's 37 paragraphs long, if you see a Taking Cactus out there in the wild..

 

[TalkingCactus]

Stosh, Andy Thatcher, Pipes, Greykin, et al: Thank you for your contributions! And a big HELLO from sunny Paradise Valley (Phoenix area), Arizona!!!

Real simple rule of thumb (and yes I understand ohm's law, just got too lazy to keep doing the math in my old age ) Resistance + 2 =voltage for ~ 8 watts power. e.g. 1.7ohm@3.7v = 8.1 watts, 2.5ohm@4.5v=8.1watts, 3.0ohm@5.0v=8.3watts. (8-9 watts is really nice to me)

On fixed voltage batts, find something in the the right range for your "sweet spot". For VV devices start at resistance+2 volts and adjust to fine tune.

 

[MickeyRat]

Can you explain this ? Are you multiplying the 3.7v of the battery by itself ?

The answer is yes.

It comes from two formulas. The first is ohms law V=IR Where:

V = Volts
I = Amps
R = Resistance in ohms

The second formula is the definition of watts that W=IV

With a little algebriac trickery on Ohms law you get I=V/R. Replace the I in the definition of watts with V/R and you get (V*V)/R=W.
