What does "resistance" in regards to clearomizors ?

[Steelgirl]

I am buying some spare clearomizors and description says "2.8 resistance". I've seen that resistance reference in other sites selling clearomizors. not sure what it means. is a low resistance good or a high number?

thank you

Resistance refers to the resistance to electrical flow and is measured in Ohms.

What is "good" depends on you. Basically a lower resistance means higher power output and a higher resistance means a lower power output.

Power is a way to measure work and in our case that means power is heat and vapor production. Power is measured in Watts. You can find the power you are vaping at by squaring your battery voltage and dividing by the resistance of your clearomizer. P=V*V/R.

So for replacements use your current clearomizer resistance and determine if you want the same vapor (and go with the same resistance), or a cooler vapor (and go with a higher resistance), or a warmer vapor (and go with a lower resistance). What's good for you is the best one to get.

mod information would help to answer the question better. Hoosier is correct. Voltage an resistance/ohms is a balancing act. You try to balance them to get the wattage you want. That is easy to do by using a simple chart.

It has a vape chart and a calculator built in.

This is the most simplistic explanation and is addressed to new vapers mostly or vapers who are happy within the recommended "just right" power zone (4.5-8.5 watts). If you are using dual coil atomizers or are interested in high wattage vaping, it's a different conversation altogether. You will also have to understand the concept of amp limits and how it applies to high power vaping.

Ohm's Law as it pertains to vaping is really not that complicated--and it's very useful when you want to know what you're doing.

Voltage and wattage are often misunderstood by new vapers. Wattage is the power (heat, sweet spot) that your PV (battery and atomizer) generates. Wattage = Voltage (of your battery) squared divided by Resistance (Ω) of your atomizer [P=V[SUP]2[/SUP]/R]. If you're not good at math, don't worry, use this easy calculator:

Of course, if you own a VW (variable wattage) device, you don't really need this calculator because your device will do the math for you.

The wattage you want, especially at the beginning of your vaping career, should be somewhere between 4.5 and 8.5 Watts. Anything lower than 4.5 watts may not vaporize your juice properly and will not produce enough warmth and vapor. Anything above 8.5 watts increases the risk of burning the filler in your cartomizers (if you're using them) and even some juices, especially the delicate ones.

There are, of course, other variables, like eliquid and JDD (juice delivery devices) that you're using on your batteries. Seven watts on a filler type cartomizer may feel different than the same 7 watts on a fillerless clearomizer or a dripping atomizer. The same is true for different eliquids; tobaccos, chocolate and coffees generally require more wattage (heat), while fruit and other delicate flavors do better with less heat. Everyone's sweet spot is different--those are just very general guidelines.

Experiment and you'll find your own bliss in no time!

The chart below is a good guide to safe vaping, even though some think it's a bit conservative.
