The Good Doctor is on a roll.
"The electrical physics don't matter. Because we are holding power constant, they are irrelevant. Which is the answer to the OP's question.
The BUILD's physics matter, which, in the terminology of the OP, means the build matters but not the amps."
This is the main reason I love my Provari and will never get a mech or do sub ohm. My understanding of matters electrical and mathematical are rudimentary. I know enough to check the ohms of my coils, use AW batteries and listen to my Provari. And to come here and ask questions and listen carefully to the advice given.
I probably could read and learn enough to do these things successfully. I enjoy my equipment and the vape I have now. I luckily do not feel a need to push my limits.
