Basically, resistance is the factor (in ohms) that says how much current (in watts) goes thru the wire, the more current, the more heat. More heat means more vapor and usually more flavor. A lower resistance atty let´s more current flow thru the wire in the atty or carto.

Small batts don´t work too well with LR atties ´cause they discharge too fast, making them fail. Be sure to use LR only if your ecig is rated for it.

Here's an easy explanation, I think.

Your atomizer or cartomizer heats by using watts, like a light bulb. The more watts, the hotter the heat and the brighter the bulb.

Most juice tastes best between 6 and 10 watts being used by the atomizer coil (or cartomizer coil).

So, to find out how many watts your coil is, you can't look at it like a light bulb because it depends on the voltage of the battery.

The simple fomula is: Volts X Volts / ohms = Watts.

If you have an eGo-T or an eGo-C, your battery is 3.4 volts.

If you use a 1.7 ohm atomizer, the formula woud be:

3.4V x 3.4V / 1.7ohms = 6.8 watts.

If you plug the numbers in the formula, replacing 1.7 with whatever resistance (ohms) your atty is, you will see that the lower the ohms, the higher the watts, and vice-versa.

If you change only the volts, the higher the volts, the higher the watts (and vice versa).

If you use too high of a voltage, or too low of a resistance, the watts will be so high that some juice will taste burnt.

If you use too low voltage or too high resistance, the watts will be too low and the vapor will be weak.

That formula's pretty useful. I'll definitely keep that in consideration when dialing in my VV device. Thanks!

If you use too low voltage or too high resistance, the watts will be too low and the vapor will be weak.

That formula is completely unnecessary.

INSTEAD you can reference this table here whenever you want to know which resistance to use (aim just below the red line if you like to push the envelope for heat and vapor production): http://www.e-cigarette-forum.com/forum/tutorials/260292-selecting-cartomizers-match-your-battery-temperature-preferences-excel.html

More voltage with less resistance doesn't just equal a "burnt taste", it increases the heat of the vapor and lowers the lifespan of the coil (the coil can melt). The idea is to find the right ratio of voltage to resistance and stay within that range no matter how much you scale it up or down. That table I linked does all the work for you. Easy button for the win!
