Votlage Drop vs. Higher Current

[tom_chang79]

Ok, watts is watts. We equate electrical heating in terms of Watts, which is a composite number of dotting Voltage with current.

We can achieve the same wattage using different resistance (ohms) in coils, but how does it really "feel" when vaping at same wattage but different coils?

For instance, does 6-Watt vaping with 1.8-Ohm coil vs. 6-Watt vaping with 2.2-Ohm coil "feel" and "taste" different?

I'm trying to wrap my head around it with some logic.

Given the same gauge of wire. Doesn't the 2.2-Ohm coil distribute the wattage dissipated throughout the coil more evenly over the surface of any wick since there are more windings (length) as compared to the 1.8-Ohm coil? Wouldn't that create a more even distribution of heat for higher vapor production? Or, am I simply not seeing that at 1.8-Ohm, more heat is concentrated in a smaller area, resulting in higher temp per square area of the wick?

I'm not sure but I believe the latter is the case because the liquid is heated for a pretty short period of time so, more heat per mm vaporizes more of the liquid in the time we activate the battery.

Ah, so the way I am picturing it, from the wick's point of view, it's seeing a higher peak temperature with the lower resistance coil (since less windings) since the total "wattage" is being dissipated over a smaller surface area? The assumption is that the wick can keep up with the rate of the vapor production...

That does make sense since e-juices do have to hit or exceed a critical (or boiling?) temperature for it to transition its state into gas?

What you described is what everyone thought a VW would be like when they first hit the market. On Paper this would seem so but in real life you have to adjust VW mods just like VV mods to get the ideal vape from different resistance coils.

It depends how the resistance is achieved. If you shorten the coil then yes, you will get a "hotter" more responsive vape. If you widen the gauge of the wire however, you will get the opposite.
