want to know what diff ohms n lr n standard resistance and stuff. just want to know what everything means!!

[dman87]

hi
so i am a noob. i have only been using an egoT since i started vapin and i want more toys for my vapin hobby now. i do not know what ohms and all the other terms in the attys mean.
i want to get a provari and a map tank on it. but do not know which one to buy. so the question is
what is the different ohms mean?? how does lr and standard attys work on diff volts or what volts work best for it??
can someone please tell me what all the different things about attys and whatever i need to know about it!!
thanks !!!!!

voltage - the strength of the battery. Given the same ohms atty a higher voltage battery will make it hotter

ohms - the electrical resistance of the atty or carto. lower ohms run hotter and cannot be used on slim batteries. lower ohms also use up battery charge faster.

mah - the length of charge of a battery (100mah being about an hour of moderate vaping w/ a standard resistance atty)


I believe for a variable voltage device that goes above 3.7v you don't want to use low resistance atomizers. For high voltages devices - the standard resistance atomizers are their low resistance atty and the HV or HR attys (usually 3.4ohms+) are their standard attys. If you put a common low 2's LR atty on a device that goes to 5-6v and crank up the voltage you are likely to pop the atty and kill it.

This is all just from what I have read here. I do not own a VV device.

That about covers it but, I will say that some people do kick up the voltage on an LR (Low resistance lower ohms) atomizer. I do have a VV device and I think they're crazy.

With a provari, you can use just about anything. You're going to have to try things till you find what you like though. ohms/volts is almost as subjective as juice flavors.

I do have one suggestion since you don't seem to know a lot about what you are getting into. You might want to go to madvapes and pick up a cheap VV box mod and try it before spending the money on a provari.

Agree with MickeyRat, get a VV at madvapes, and some Dual coil atos, and you can go with it wherever you want. At 3.5V very strong flavour and medium TH, at 4 volt TH increasing, At 4.5 Amazing TH and still good flavour, and at any V clouds of vaper.

I just bought my first 5v box mod and love it. Works fine with regular cartos and works great with the 3.2 ohm I just bought. I hope dormouse is right about longer battery life with higher ohms. It makes sense. Check this one out.

Just for fun, and others that read this thread... dormouse summed it up. Another analogy that helps for the electrical part:

Voltage = water pressure (push).
Amps = pipe diameter (bigger = more flow at any given pressure)
Ohms (resistance) = a flow restricting item ... higher value is more constricted (less flow due to more resistance).

So.... they all work together. There's a set of formulas that describe it (Ohm's law). However, there's really one most important formula for vapers:

Voltage squared / ohms or V * V / R

This gives you watts (heat). That will tell you how hot a given combination of voltage and atty ohms is. Easy. Now with vv, you can dial in the voltage for whatever atty you have. Just start low and work up to a "good vape". Usually 7-8 watts is good.

oh i see. i think im getting it now. well thanks for all the answers i got

Example:

"The best you will get out of an eGo battery is 0.65A or 1A that is with 650 and 1000mAh respectively. A 1.5 LR draws 2A on an eGo battery.


The ratings 650mAh and 1000mAh do not state the maximum current output of the battery. Rather, they state how long the battery will last given a particular current draw. For example, a 650 mAh battery can deliver 650 milliamps (0.65 amps) for one hour. The 1000mAh can deliver 1000 milliamps (1 amp) for one hour. So, if you're using a 3.7 Volt 1000mAh battery, it works out like this:

I = current (amps)
V = voltage (volts)
R = resistance (ohms)

3.7 volts across a 1.5 ohm atomizer:

I = V / R

I = (3.7)/(1.5)
= 2.47 amps = 2 470 mA

This is the current that the atomizer will draw from the battery. To find out how long the battery can deliver this current, you do the following:

time (hours) = mAh/mA
= (1000)/(2 470)
= 0.405 hours

Therefore, with a 1.5 ohm atomizer, a fully charged 1000mAh 3.7 volt battery will last for 0.405 hours (24.3 minutes) of constant use.

Separating this 24.3 minute time frame into 5 second "draws,"

24.3 minutes * (60 seconds)/(1 minute) = 1458 seconds

1458 seconds * (1 draw)/(5 seconds) = 291.6 draws

You can do your own math based on how often you tend to take a draw to determine how long it will last you. My own personal experience is that, with a 650mAh 3.7 volt battery, using a 1.5 ohm atty lasts me about 24 to 36 hours while using the standard 2.2 ohm atty lasts me about 48 to 60 hours."
