So in my adventure into rebuilding my AeroTank dual coails into single coils, I have had a few that have come in at 3+ohm. Although I have torn them back apart, and rebuilt to get to my desired 1.7ohm range. It made me start thinking, why are the lower ohms better than the higher ohms?
Why is 1.5ohms-2.0ohms better than 3+ohms?

Lower ohms means lower resistance, which means it heats up more with less voltage.
If you are stuck with a 3.7volt battery you would want lower ohms to get the most out of the carto.
However if you had a variable voltage battery you can adjust to the ohms of the carto to match the performance.
For example if you had a 3ohm carto you would bump the voltage up to 5volts+.

1.5 Ohms is not inherently better than 3.0 Ohms, but it might work better for you, depending on your particular setup.
What I'm not sure of is if you had:
1.5ohm coil with 3.7volt battery
3ohm coil with say a 5.5volt battery
Would the higher ohms and voltage produce more vapor or a warmer vapor since more voltage is being consumed?
Or is the performance identical once the ohms and voltage are matched respectively?

A resistor dissapates energy as heat, basically the amount of heat generated can be expressed in Watts (W) (standard unit of POWER). Ohm's laws give: Power = Voltage x Current ( P = V I ). Current is goverened by both Voltage (V) and Resistance (R) as V = I R, so combining and expresing power in terms of voltage and resistance: P = V^2 / R.
Thus a 1.7ohm resistance with 3.7V => 8 watts power, to have the equivalent with a 3 ohm resistance would require voltage of:
V = sqrt(P R) = 4.9 V
This is of course all theoretical values, the construction and geometry of the atomizer likely will effect the non-empirical vape nature of the atomizer.

Don't you have it backwards? The lower the ohms, the lower voltage you run. The higher the ohms, the higher the voltage?

I might be confused with volts and watts.
Ohms = measurement of resistance of a circuit
Volts = measurement of the potential energy of a circuit
Watts = measurement of the amount of work a circuit can do
Ohms are Ohms regardless of the voltage being applied. Watts would change, ohms would not.

If your talking about watts you shouldn't have to change it to get a similar vape.. If you're referring to Voltage then you do have it backwards. The higher the resistance the higher voltage you have to run.
In terms of wattage though
1.5 ohm coil set to 3.2v = 7watts
3ohm coil set to 4.5v = 7 watts
Should give you a similar vape..
