Hi , I have just gotten into the Ibtanks I have 3 now so I was fooling around with the volts and watts
first thing though I have Halo tribecca in 1 tank vaping at 6 watts and 8watts with Bobas bounty in the other .I wasnt getting a great hit hit off
the tanks with bobas so i started fooling around with the volts it has a 2.0 single coil carto so i did the plus 2 which comes to 4 volts and it is vaping well .So here is my question 4 volts on a 2.0 carto equals 8 watts on the online calculator when i use it at 8 watts the hit is kinda crappy but on 4 volts its great It doesnt make sense to me it all boils down to 8 watts in the end the only number that is different is the amps which at 8 watts is 2.0 but on volts its 1.8 does anyone have idea what I am talking about this is driving me insane LOL sorry about the rant take care all

Volts x Amps = watts
so you can increase one and decrease the other and end up at the same wattage.
if we imagine a garden hose in our mind.
this hose is the coil wire. (or any conductor for that matter)
and the water flowing in the hose is the flow of electrons.
Volts is like the water pressure
Amps is the speed the water is moving at
and resistance or Ohms is the back pressure caused by friction.
Volts X Amps = watts
the watt is a unit of power.
as resistance increase, Amps will decrease.

a while back there was a thread about how "wattage" is not everything. you might find your coil preforms better with a lot more voltage or electrical pressure and less speed or vise versa. it all just depends.

example
6 volts x 2 amps = 12 watts
2 volts x 6 amps = 12 watts

Wow great explanation that does make total sense .
I was wondering why while reading a lot on the net that most people suggests watts I was thinking to myself why does any
APV manufacturer still bother making mods with volts , But this makes total sense to me thank you for taking the time to make this clear I may start testing out other juices and tanks with volts instead of just using the wattage

Good analogy, but instead of relating current (amps) in terms of speed, I would think of it in terms of how MUCH is flowing. The bigger the hose, the more water that is flowing in terms of volume not speed, IOW the less resistance you have to current flow then you have more electrons flowing

In actuality all VW mods are automatically adjusting your voltage according to the measured resistance to give you the desired wattage. Amps and watts are determined by the input voltage and resistance of the circuit. Voltage and resistance are what we control and these 2 values will determine the amps and watts. Wattage is a measurement of power or work produced, it is an output, not an input.

"The bigger the hose, the more water that is flowing in terms of volume not speed"

the diameter of the wire effects the resistance, because you have more atoms that can freely exchange electrons.
only the electrons in the valence orbit freely exchange from one atom to another..

the size or gauge of wire has nothing to do with the "volume" of electrons being transferred.
we would need to look at a couple of variables in order to calculate the volume of electrons being transferred

Electrons only flow on the surface of the wire..
lets say we have a solid copper wire that 10 gauge
and we have a multi-stranded copper wire that is 10 gauge
the multi-stranded wire will have less resistance and can handle more power (do to an increase in surface area) than the solid wire without becoming over heated and melting the insulation and starting a fire...
so the size or "gauge" of the wire does not matter so much..

also some materials conduct electricity much better than others, we would need to know the chemical makeup of the conductor in order to calculate the volume of the electrons being transferred.

Forget the amps for now. :D Maybe this explanation will help:

Disclaimer: This is the most simplistic explanation and is addressed to new vapers or vapers who are happy within the recommended "just right" power zone (4.5-8 watts) and use stock coils.

Ohm's Law as it pertains to vaping is really not that complicated--and it's very useful when you want to know what you're doing.

Voltage and wattage are often misunderstood by new vapers. Wattage is the power (heat, sweet spot) that your PV (battery and atomizer) generates. Wattage = Voltage (of your battery) squared divided by Resistance (Ω) of your atomizer [P=V[SUP]2[/SUP]/R]. If you're not good at math, don't worry, use this easy calculator:

Online Conversion - Ohm's Law Calculator

Of course, if you own a VW (variable wattage) device, you don't really need this calculator because your device will do the math for you.

The wattage you want, especially at the beginning of your vaping career, should be somewhere between 4.5 and 8.5 Watts. Anything lower than 4.5 watts may not vaporize your juice properly and will not produce enough warmth and vapor. Anything above 8.5 watts increases the risk of burning the filler in your cartomizers (if you're using them) and even some juices, especially the delicate ones.

There are, of course, other variables, like eliquid and JDD (juice delivery devices) that you're using on your batteries. Seven watts on a filler type cartomizer may feel different than the same 7 watts on a fillerless clearomizer or a dripping atomizer. The same is true for different eliquids; tobaccos, chocolate and coffees generally require more wattage (heat), while fruit and other delicate flavors do better with less heat. Everyone's sweet spot is different--those are just very general guidelines.

If you are using dual coil atomizers, things get a bit more confusing. Dual coil atties consist of two coils configured in parallel, which means that a 2.1Ω atty is really two 4.2Ω coils--so you have to calculate your wattage based on the 4.2Ω number--not 2.1Ω--roughly. Dual coil atties require more wattage than singles, but not quite twice as much. They produce more vapor due to increased surface. I usually increase the power (wattage) by 30-50% when using dual coils; for example, if I like 6 watts with a single coil atty, I start at 8-9 watts with a dual coil atty. That's just my preference--YMMV. When in doubt--start low and adjust up as needed.

If you are interested in high wattage vaping, that's a different conversation altogether--and not my area of expertise. :)

Experiment and you'll find your own bliss in no time!

The chart below is a good guide to safe vaping, even though some think it's a bit conservative.

The size of the wire absolutely matters for amperage. You can only push so much current safely in smaller diameter wire. The larger the diameter of the wire the more surface area available for electrons to flow.

Yes
as amperage increases
resistance decreases
and vise versa
as resistance increases
amperage decreases
bigger wire / multi-stranded - more surface area - less resistance

Amperage is not the volume of electrons it is the speed the electrons are traveling at.

I was referencing your analogy for current flow compared to water flowing through a garden hose, so in that analogy there is a greater volume of water moving in a bigger hose. Amperage is not a measure of volume or speed but how much current there is.

1 ampere = 1 coulomb / 1 second

Current has to do with the number of coulombs of charge that pass a point in the circuit per unit of time.
