Can you provide a simple explanation of what vapers need to know about Ohms? - Please keep in mind that most new vapers never heard of 'ohms'.

Most simply stated, Ohms are a measure of resistance. The lower the resistance (Ohms), the higher the current draw (Amps) will be required from your battery. The more amps that are drawn from your battery, the faster your battery will drain. It is best to find a 'happy' balance for a good vape with battery longevity. It used to be recommended that beginner vapers not go below 1 ohm, but with the newer mods available today, and the readily available pre-built coils that is not so much the case. It should be stated that most beginner vapers stick to no lower than 0.5 ohms and that they also use a regulated mod that is built to handle such coil builds.
Ohms are a measurement of the resistance of the coil/s
For vaping most will be between 0.3 - 2.4Ω
The lower the ohms the more watts required for a reasonable vape ( can be dependant on atomiser being used)
The ohms of your coil/s will determine the watts and volts depending on which one you set on your mod.
eg 1.5Ω coil at 10.5 watts will be 3.97 volts. Put in a 2Ω coil at 10.5watts that will be 4.58 volts.
Regulated mods usually display both the watts and resulting voltage and the resistance.
On a mech mod you need to pay more attention to the amps being drawn from the battery.
1.2Ω on a fresh battery say 4.2 volts will be 14.7 watts and drawing 3.5 amps from the battery.
Go down to a 0.5Ω on a fresh battery and its 35 watts and drawing 8amps from the battery.
The battery needs to have a higher amp rating then what the coil/s will be drawing from it.

Best way to have it described is search for Ohm's Law. There are different equations relating to Ohm's Law, but the basics are in the 4 variables of it, Ohm's (Resistance), Current (Amperes), Volts, and Power Output (Wattage). All 4 variables shake hand in hand with each other, change 1 of them, the others are changed as well. Most of my calculations is in regards to Voltage, fresh charged 18650 Lithium Ion battery is about 4.2v, so this variable is always one of the 2 variables I use as set. So, as resistance in your electrical decreases, with a set voltage, you will notice Current and Power Output increase, this is especially true when dealing with mechanical mods and rebuildable atomizers, as resistance drops, amps and wattage increase exponentially.
We use these variables to determine what we are requesting a battery to deliver at a set resistance and full charge, especially amperage draw. Li-Ion batteries have two amp ratings, a short burst or pulse rating, and a continuous discharge rating. For example we have a 0.5ohm dual coil, at 4.2volts fresh charge the battery must be able to deliver at least 8.4amps continuous discharge, or it will suffer damage, and/or if way over its rated CDR could potentially explode or vent a hot jet of gases when it goes into thermal runaway. Thus why we stress battery safety and learning how to use an Ohm's Law Calculator to stay in the safety ranges a battery can safely deliver for our needs.
Most of use generally build our coils setups to where we are not asking more than 50 to 75% CDR from a battery, example Sony VTC4, 30amp CDR it can safely deliver, I personally would not build lower than a 0.25ohm coil config, a Samsung 25R has a 20amp CDR, I would build no lower than a 0.45 or 0.5ohm coil config
Examples:
4.2 Volts, at 2.0ohms resistance, equals 2.1 amps, and 8.82 watts power
4.2 Volts at 1.0ohms resistance, equals 4.2 amps, and 17.65 watts power
4.2 Volts at 0.5ohms resistance, equals 8.4 amps, and 35.28 watts power
4.2 Volts at 0.25ohms resistance, equals 16.8amps, and 70.56 watts power

Just a little visual with the formulas for various situations.
As you can see, there is no "one simple" answer to your question.
Your question is "too generic" for us to give a "simple explanation" that takes into account all the safety issues (with regards to ohms) that a new vaper may run into depending on the equipment they are using to vape with.
Many new vapers are starting out with more advanced setups these days.
Have you started vaping. If so, what are you using to vape with?
im not a newbie, but i started getting into ohms as ive decided to upgrade. i know ohms from my education in wave physics. in vaping, in lamens terms, it just means how much energy/heat/resistance a metal wire/coil can withstand. the reason why this is important to vaping is because the lower the ohms, the hotter the coil gets, which in turn means the more juice will turn into vapors to be inhaled. im no expert & thats about as far as i care to research into it myself. im catching up with other facets of better builds & will come back to the ohms issue at a future time. but yeah, if you want stronger hits...like the more seasoned ppl in here said, stick with regulated boxes, i.e. istick, sigeil cloupor, etc. ones that someone reputable has made. that being said, you also want to stick with tanks that have prebuilt coils available, i.e. aspire nautilus, kanger subtank, etc
i think this is correct.
i think this is correct.
ohms = resistance
water valve = resistance
lower ohms = less resistance
less resistance = water valve wide open
water valve wide open = lots of water flow
water flow = amps
therefore a low resistance load will result in a high amperage flow
and your bucket of water will empty faster

well the guys are explaining this pretty good. If you want to make sure if your resistance / OHM and your wattage are in any critical range the Steam engine does the easy sanity check.

Simple- ohms is/ was more important when more devices were unregulated. The lower the ohm the more power it would force from the battery which also made the coil or device run hotter.
With the unregulated devices too much resistance equals a weak vape.
Now with regulation a lot more common ohms arent the deciding factor anymore. It used to be you had to think ,,,,, 2.4ohms is too high and I get no vapor, but 1.5 is too low and my vape taste burned, maybe I will try a 1.8..
With todays (regulated) equipment not so much. Like with subtanks it is more for power range suggestions more then making the kit run efficiently because you can adjust the power however you want.

Simple as I can be, if you're new to vaping and don't have the depth of understanding of battery safety, stick with regulated mods and pre-built coils. Lower ohms, like sub ohming creates bigger clouds. In the very beginning you just need to make sure that the tank or coils you're using are within the limits of the battery you're choosing to use with it.
When I first started vaping I found it impossible to completely understand all of the details. Start safe, regulated mods and pre-built coils made for those mods. As you get more into vaping you'll pick up more and more information that will make more sense as you actually experience the differences.

If you're using a device with a coil with 1 ohm or above you'd more than likely be using a low powered device.
If you're using a device with a coil, or coils, with low, or combined ohm'age then you'd definitely be using a high powered device.
The safety aspect vapers need to be aware of is that low ohm'age coil circuitry has to be used with a battery or batteries with high ampage continuous discharge capability. A good example of that would be the "Sony VTC4 18650 battery" which has a genuine continuous discharge rating of 20amps.
