Hi all,
i have seen around 1/2 dozen variations of the attached spreadsheet, with resistance on the y axis, voltage on x axis, and watts calculated as W = V2 / R in each cell. Obviously an invaluable chart for anyone using vv pv's who (like me) doesn't know the first thing about electrical engineering. HOWEVER, it gives a lot of unnecessary information... If I know that a 3.0 ohm atty probably won't vape at <3.5V and will likely short at >5.0V, I would rather look at a wallet-sized cheat sheet that shows the range of safe/effective vaping than the big chart. Something like this:
1.5 ohms: min V/max V
1.6 ohms: min V/max V
1.7 ohms: min V/max V
..........
3.5 ohms: min V/max V
I want to put together a spreadsheet like that in 0.1 ohm increments and cover the whole V range of my provari. looking at the charts that are circulating around the interweb, it seems like the safe/effective range is 4W min to 8W or 8.5W max. Can someone confirm? Or, if I am way off, advise what the magic W range i should solve for is? Or, better yet, does this chart already exist?
i'll definitely post my chart if/when I make it. I think a good number of people would find it helpful
thanks and cheers,
ethan
