Volts, Ohms, LR and HR Atomizers. What does it mean to me.

[Vega]

Hi ECF! I'm fairly new at this and am starting to understand some of the more technical aspects of vaping. Can someone please explain the relationship between what voltage my battery is and the ohm rating on my cartomize? What is the difference between a low resistance atomizer and a high resistance atomizer? How does the combination of these two affect my vaping experience?

Thanks!

P=V*V/R

Vapor Production=Heat=Power=Voltage squared divided by Resistance in Ohms. (As long as the power supply has the capacity to supply enough current.)

It's all about the power and the average sweet spot seems to be 8 Watts, or there abouts. Some, like me, range closer to 12 Watts. Some flavors I like higher and some I like lower, but if I start out at 12 Watts, I can tell which way to go. Hint, if it tastes burnt or metallic, power is too high.

Lower ohms go with lower volts. Higher ohms go with higher volts.

There's a thread here on the forum that goes into great detail and also has volt/ohm/watt charts in the thread. May take a little searching but it's very well explained.

Since Hoosier provided the equation for Ohm's Law you may like these calculators that can slice and dice the equation various ways:

Lower ohms go with lower volts. Higher ohms go with higher volts.

I like that Spicy. Easy.
The mathematician in me still likes Ohms Law via Hoosier tho.

Here is a handy-dandy chart to help.

The lower the resistance of a heating element, the more heat is produced when electric current is applied. A low resistance atomizer or cartomizer will be hotter than a regular resistance atomizer given the same current.

There's another way to make things hotter, and that would be to increase the voltage to the heating element (carto or atty).

I think most of us find that more heat produces a better vape. However, if things get too hot then you get an awful burnt taste. This burnt taste could be the equipment, it could be the juice... but you'll know for sure when it happens. It's not a pleasant experience.

You can also fry your atty/carto if you crank to high a voltage. Like running a 1.5ohm at 6 volts for instance.

So Let's hold something constant. If I'm using a 3.7v regulated battery (Fill in the blank):

a 2.4 ohm vs. a 2.8 ohm cartomizer is _______ (lower/higher) resistance, the amount of vapor produced will be _________ (lower/higher), and my battery life will be________ (shorter/longer).

2.4 is lower resistance than 2.8
It will producr a bit more vapor and a hotter vapor
Your battery life will be shorter the lower you go with resistance
2.4 will give you 5.7 watts
2.8 will give you 4.9 watts

Less is less, Ohms are not sheet metal gauges.

P=3.7 V*3.7 V/2.4 Ohms=5.7 Watts
P=3.7 V*3.7 V/2.8 Ohms=4.9 Watts

The higher Wattage will drain a battery quicker than a lower Wattage.

Since Watts=Power=Heat=Vapor Production then more Watts means more vapor. (More is more and less is less)

True, but some like more and some like less.
Some like a hot vape and some like a cool vape.
For me...less is more

 

[Hoosier]

Nah, less is good and more is too much for you.

Like spending time with the in-laws?
