Variable Wattage,and resistance, the math doesn't make sense to me...

I recently got a itaste vtr, I love it, it's great. I have been vaping on a reogrand for the last 2-3yrs. This is my first variable mod.

Maybe I am just making the wrong assumption, I assume that the VW mods adjust the voltage to produce a specific wattage. In other words, the mod self adjusts the voltage to get a set power output.

The math
V=IR
P=IV
where V is voltage, I is current, R is resistance and P is watts.

Below is our new formula for power.
P = (V^2)/R

If power is constant, which it is on these mods. If I set my wattage to 10 watts. It's not going to move from 10 watts and lets say i use a 1.7ohm resistor. I get this

10 = (V^2)/ 1.7

This will produce 4.1 Volts.

The only thing that's going to change is the voltage, it's the only thing that can change. Lets say I use 2.0ohm resistor the volts would be 4.5 volts.


Now here's my question...I have been using a 2.0 ohm iclear 30s tank. I put on my 306 to test a juice. The resistance was 1.6ohms. The hit is a lot stronger with the 306 than the 2.0ohms resistor.

The question is why? It should all be the same. I see people doing all these coil configurations, dual coils, tri coils, dragon coils, nano coils etc.. From a math perspective it should all be the same output. So why aren't they all the same?

Because it's not just about watts. All factors of an atomizer combine for the relative experience. Coil design and surface area, wick design, and airflow dynamics are all important. The 306 is probably just a better design for you.

What LucentShadow said ^^^

A single coil will perform differently than a micro which will be different than a dual coil which will be different than a dripper which will be different than a cartomizer.

Wattage, voltage, resistance, coil design, atomizer design plus may other thing factor into the vape experience.

Plus wicks, cotton, whatever the case saturates differently. The way I see it is, I use volts for adjustment because its quicker, less numbers to go thru lol, but watts are "basically" 2 times your volts. They smoke different to me tho. Some one told me its a matter of the way they drain I think, volts pulls the same, and maybe watts adjusts more to the resistance? But I do not know if that's accurate.

Okay thanks, that makes a lot more sense.

Thanks everyone else too.

Watt is 2x volts divided by the resistance

The variable voltage I believe work like this. Lets say you have a non variable voltage 6 volt mod. As time goes by the battery drains out then the voltage goes down. The hits become weaker. This is how the variable voltage works.

When using a variable wattage device, it changes the volts, as time passes and the volts would go down on the battery, the mod increases the volts so it would produce the same amount of watts. This just means once you set it at a specific watts, the hits will be consistent. This is what makes makes sense looking at the math. The devices might work differently, but i doubt it.
