Please answer my question!!!

[BobbyDidge]

Ugh can someone please make this clear to me, I have been vaping for 6 months and spent thousands of dollars. It totally becomes a hobby. My only question is what the he11 is amps. I understand v*v/ohm= watts or watts*ohm=square root of voltage. I also know the "sweet spot" is considered 4-8.5 watts. So where does amps and 2.5,3,4,6ect. amp switches do what are they stopping you from doing!?! How do you find the amp!? I go online to watt to amp converters but it can't be right cause the lower I put the v or watt the higher the amp and I'm pretty sure it's opposite.

Also what's the equation for dc's when finding watts?

Please I know it's probably been written in here SOMEWHERE but six months and still don't know help!!!

check here for the formulas they will allow you to properly calculate for power or current

I'm lazy, I just use this-
Ohm's Law Calculator

 

[gthompson]

watts = (volts * volts) / ohms
amps = watts/volts

The short answer is Limiting the Amps keeps you from Destroying your PV and or Damaging your batteries.

THANK YOUUUUU EVERYONE!

Any word on dual coils?

 

[rl0156]

the coils in our PV's are basically resistors for all intents and purposes so the theroy and formulas here Resistors in Circuits - Practice - The Physics Hypertextbook will get you the info you need to figure out the power requirements for a dc cart

great find , just bookmarked that page for my own use thanks

If Amps = Volts/Resistance, then it should be safe to use a dual coil on a device with a 2.5 amp limit IF you never run it any higher than 3.7 volts, right?

Of course, there's always a +/- of 0.2 ohms. So, better to stay below 3.5 to account for variance in manufacture.

Sound about right?
