Ohms/volts/watts

[bulldog63h]

If you've never messed with electronics and such it is confusing.

Ohms is resistance to the flow of electricity. Consider it in plumbing as to the size of a pipe or hose, the longer or smaller it is the more resistance to the flow of water.

Volts is the driving force of the electricity. Same as what water pressure is, the more pressure the greater flow.

Watts is the amount of electricity flowing. Same as gallons of water.

A good way to figure the amount of wattage needed to properly get the coils burn correctly is to use the formula of:

(Volts x Volts) divided by Ohms = wattage.

On my iTaste SVD battery mod I can adjust both wattage and voltage to get the right amount of vape. It takes some tinkering and adjusting 'till you find that sweet spot that suits your taste.

Here is a handy chart you can download and use for reference. It's from www.reddit.com

Anywhere in the green shaded area should be good for "suggested optimum vaping".

Outstanding analogy. OP, the main point to remember, adjust voltage or wattage to what tastes best to you. Knowing the technical aspects of electricity is relatively unimportant.

Another analogy:

Light Bulbs 60W and 100W bulbs the 100W bulb will be brighter
both bulbs run off of 120V the 60W bulb has a higher resistance thus decreasing the current thru it
the 100 watt bulb has less resistance and allows more current thru it thus a hotter bulb to touch ( even tho both bulbs will be hot to touch )
Now consider some device that measures the brightness of the bulb ( say a light meter that is attached to a dimmer switch).
You turn on the switch to the 100W bulb and set the device to say 50W light output. The unit then lowers the voltage automatically to make the 100W bulb act like a 50W bulb. This is the WATT mode setting on the VW mode.
Lets turn that switch back on but without the sensing device, but with the dimmer switch still active. We plug the 100W bulb back in the socket and lower the Dimmer switch to make the 100W bulb act like a 50W bulb, ( the dimmer switch lowers the voltage ) This is VV mode.

So in effect both modes adjust the voltage, VW does the volts adjustment automatically while the VV is done by you. The advantage of VW setting is that as your coil ages the resistance changes a tad, and the controller will adjust the voltage accordingly. In VV mode, as your coils resistance varies, your wattage will change too.

Thanks for the info everyone, can't wait to try out my first variable!
