Volts and watts?

[jaketheduck]

Can someone please explain to me the difference between voltage and wattage? For a long time I thought the more voltage would equal the most vapor, but I'm probably wrong. Why do people drool over big expendive variable voltage and wattage mods? Does wattage or voltage give more vapor? A hotter vape? I'm just overall confused. Thanks in advance!

Basic Electricity is a good primer on Ohms Law to get you started. ;-)

This is a great explanation from another ECF user:

Watts equals the relationship of volts and ohms. Volts squared divided by ohms equals watts. Neither can exist without the other. Watts equals the "power" or "work" being used or done.
In other words, if you use watts to adjust the power you are changing the voltage to get there, if you are using voltage, you are changing voltage to get the watts you want.
Play around with this calculator for a bit, Ohm's Law Calculator start with 8 watts and 1.5 ohms then change it to 2.5 ohms at 8 watts and see how the voltage changes to achieve this. Also note how the amperage changes as well, this will determine how long your battery will last, less amps, longer battery life, to a point! But I've got you confused enough we don't need to get into the myth of VV and VW battery run times!

in a nutshell in regards to vaping here is how I normally explain it

VV (variable voltage) will allow you to raise or lower the voltage that goes to your coil to generate a higher or lower wattage (heat) based on the known resistance (ohm rating) of your atomizer coil - you need to know the actual resistance of your atomizer coil (most factory coils read +/- .2 to .4 ohms from what they are listed as (usually + - I have had 1.8 that are actually 2.8 - this is why I rebuild my own)

VW (variable wattage) will let you set wattage going to your atomizer coil - no need to know what the resistance is, the device will read it and set the voltage automatically for you

or there is the garden hose analogy - water = Volts, hose diameter = resistance, volume of water = wattage/power

small diameter hose = higher ohm coil = higher resistance = less volume of water at a set flow = low wattage/power

all (or most) APV's have a protection circuit built in to them to not fire if an atomizer with too little resistance is installed (usually anything below 1.3 ohms) as too low resistance may cause bad things to happen with your batteries (shorted batteries may go into a thermal runaway and vent (gets really hot and explodes))

hope this helps

I read over the links, and I still am confused as to why? Will more wattage and voltage give more vapor production?

Wattage is ultimately what you are looking for. More watts = hotter coil and more vape.
You increase wattage by either increasing the voltage or reducing the resistance of the coil or both. Conversely, reducing the voltage, and/or increasing the resistance will reduce the power (Wattage).

If all were perfect and all clearos were exactly at the ohms as advertised using voltage would be great BUT many cartos/ clearos can be out by as much as 10- 20% + or - ohms wise. When using wattage the APV will automatically calculate the exact same power level regardless of the ohms of the carto/ clearo. Having said that realize some juices taste better at a higher or lower voltage/ wattage.
Realize also as times goes on your ohms will change due to wear, tear and gunk on the coil.

yes, the higher the watts the hotter she burns the more vapor is created, provided you have an atomizer that can wick enough juice and supply enough air so that you don't get dry nasty hits and burn your wick, causing choking and gaging. It has everything to do with the right wick build atomizer and device. High watt vaping is for advanced users. I vape at a minimum of 15 watts and some set ups over 30 watts. Most atomizers can not handle more than 10 watts, usually need a quality rba or rda to break the warp 10 barrier.

Volts squared divided by resistance (ohms) equals watts produced. Then there is the whole amp draw consideration of your battery and......
