Ohm's Law
Ohm's Law defines the relationship between power, voltage, current, and resistance. The various possible formulas for Ohm's law include the following:
Where
P = power in watts
E = voltage in volts
I = current in amps
R = resistance in ohms
P = E2/R
P = I2 * R
P = E * I
Power will determine how your juice tastes. So, VW will regulate the device and hit your target without you calculating Ohm's Law. The Vamo and Tesla for example are VW. This is a newer technology.
VV will attain the same goal. However, you are adjusting volts so that you will hit your target wattage/power. From the formula, you can see how voltage relates to resistance of the atomizer, to attain your target wattage. So, VV requires an extra step. The Provari and Ego Twist are VV, for example.
Devices that are VW are by definition also VV and the readout can be changed from VV to VW (current to power).
I just turned up my Tesla (VW) to vape a chocolate at a higher wattage, than when I had a fruit ejuice in the tank, which requires a lower wattage to not taste burnt. On my Provari, I would test the resistance of my atomizer, then adjust the voltage to hit the target wattage.
You can use this chart as a shortcut; it just won't tell you the sweet spot for your particular juice.
