I really need help understanding coils! Please Help!

Resistance is finicky to understand, and much harder to explain, so bear with me!
First, the bigger the wire, the less resistance, the smaller the wire, the more resistance. The shorter the wire, the less resistance, the longer the wire the more resistance. Easy enough so far.
So the less coils, the less resistance you have, depending on wire size. a smaller wire can accomplish a higher resistance with less coils than a larger one with more. So it comes down to sizing everything to match the desired out come.
The resistance is what cause the coil to heat, which causes the juice to heat, which creates vapor. The coils are used to heat the juice, and to create a usable length in the wire. Doing two parts, creating the desired resistance, and heating the wick and juice to create vapor.
Low resistance is used on low voltage units, the Silver Bullet for example.It puts out 3.7 volts or so, a lower resistance will create more heat in mods like that.
Higher resistance is used in VV/VW units, like the Lava Tube, Provar etc.you can crank the volts, or watts up to get the throat hit and flavor you want.
But there is a price to be paid with low resistance atty's! The lower the resistance, the closer you are to a direct short, and use more power from the battery.
I like to use a lantern as an example, start out with three propane bottles. Set the lantern up and crank it up as bright as it will go, a low resistance atty, it will only burn for a few hours, but it will be bright, and you will get lots of vapor and throat hit.
Take the next bottle and set the lantern about half way, a medium resistance atty. It will burn for several more hours, giving usable light, decent vapor, moderate throat hit.
Take the third tank and set the light as low as you can, a high resistance atty, once your eyes adjust it works and will burn all night and then some, not much vapor or throat hit.
In the above, we used the same amount of energy, in different ways, when you get to VV/VW PV's it all changes! You can get the same wattage out of a higher ohm atty, at a higher voltage, BUT use less power from the battery. It all comes down to Ohm's law and learning how to maximize the power you have at hand. Like I said, hard to explain!
