Understand Voltage, resistance, and power, but what about current effect

[brawas]

I understand Ohm's law, and setting the proper voltage based on the resistance to get the wattage (power) you want. However, you can achieve the same power, with different current (A). I understand that will affect battery life, but how does it affect your vaping experience?

Example:

1.6 ohm coil @ 3.6v will give you 8W and use 2.2A of current

3 ohm coil @ 4.9v will also give you 8W, but it will use 1.6A of current

Essentially, the lower the resistance, the faster the coil heats up. A 3 ohm coil will take maybe 2-3 seconds to heat up to where you want it, while a 1.6 ohm coil will reach that point in right around 1 second. Yes, both will achieve the same power at different amperage - it's just a time factor, mostly. Like most things that produce heat - the more heat that is required, the more amperage that is going to be used.

So as for the vaping experience - more amperage (less resistance) = more heat per second, or more vapor production per second.

Makes sense. Thanks for the explanation. I initially thought higher resistance would be better in my case with a Provari. Being a VV device, according to the safe vaping voltage chart, I would have a bigger range to play with in the safe area. Also, longer battery life. Therefore, I found I'm pretty happy with around 2-3 ohm coils. Now I got a Nautilus and it is 1.6 ohm (which is what got me thinking about this again). At first I was thinking I wanted to find higher resistance coils (2-3ohms).

However, since I don't really need a wide range of power to play with (I mostly like vaping between 6-8 watts), and based on your explanation, I think I will like the lower resistance more. So now I'll be looking to standardize my resistance across all my tanks at 1.5 - 1.8 ohms.
