Standard resistance (2.8-3 ohms) is better suited for VV mods. They are the only type that can fully utilize the range of voltages on a VV mod. So, basically they can be used with all voltages. On fixed voltage devices. Most people use them for High Voltage vaping such as 5 or 6V. They handle the power that these mods produce a whole lot better. Meaning that the coil won't pop on your carto and atty (if that happens then it's dead). You will notice the increase in vapor, TH, and warmth to your vapor as you increase the voltage with SR atties/cartos.
Dual coil is just two coils lined up parallel to one another. They are supposed to give more TH and warmth than a single coil since they can cover much more surface area within the carto. Since both coils are supposed to be getting identical voltages. Which can also give more vapor as well. The problem with this is that they need more power in order for them to work correctly. So, something like a 1.5 ohm carto will have two 3 ohm coils in there. Meaning that you have to use them at 4.2V or higher in order to have a proper vape.
A single coil is what it sounds like. There is a single coil located either in the middle (vertical coiled carto) or on the bottom (horizontal coiled carto). The voltage that you use them on is what is transferred to the coil itself. IMO they do a hell of a better job in utilizing the power that is given to them compared to DCC. So, choosing the right ohms is crucial with these types of cartos. If you use a LR at 5V then you will definitely pop the coil and the carto will be dead.
Simple rule of thumb with matching ohms and voltages. The lower the ohms, the lower the voltage it is meant to be used with. The opposite is also true. Here's a simple list to give you a quick idea of how this whole thing works:
1.5 ohms = 3.7V
1.8 to 2 ohms = 3.7 - 4.2V
2.5 ohms = 3.7 - 5V
3 ohm = 3.7 - 6V
Just to be clear, you can use higher ohm atties at lower voltages. The disadvantage is that it will be a much cooler vape along with having little to no TH. It's your call if you want to do that or not.

To my rescue yet again Washvap. Thanks a ton. This is basically how I had it in my mind. I just really wanted to be clearly informed to avoid talking outta my rear end.
