What does the ohm do? I've always been a bit confused on this and the difference between the lr, hr and the plain old regular.
It's the resistance of an atty or carto. LR is usually 2.4 ohms and under (typically 1.5 - 2 ohm). Standard is usually 2.5 - 3.3 (typically 3 ohm). 3.5 and higher is HR or HV (High Voltage). LR is used mainly on lower voltage devices (like the ego or similar 3.7v devices) to simulate high voltage vaping (warmer vapor and more of it). Standard/Regular is used on devices that produce voltages up to 5v. HR is used for 6v and 7.4v devices. The resistance (ohm) also reflects the warmth of vapor you intake as well. So if you like a warmer vapor you go with a lower ohm at a certain voltage. If you prefer a cooler vapor, a higher ohm at the same voltage will give you that result. Also, if you often get a burnt taste when vaping it can be caused by using an atty/carto that has too low an ohm rating for the voltage you are using. For example, using a 2 ohm atty/carto at 5v may produce a burnt taste because the atty/carto wasn't meant to be used at that high of a voltage. This burnt taste is caused by the filler and/or liquid burning because the atty/carto is running too hot. Dialing down the voltage to 3.7v or using a 2.5 - 3 ohm atty/carto would alleviate this problem. It's always good to know what the ohm rating is on an atty or carto because it's an indicator of what voltage you can use it with to produce optimal results for your vaping style without getting a burnt taste.
For reference:
Typically with LR you don't want to go above 4 - 4.5v or you will start to get the burning.
With a SR (standard) 3 ohm atty/carto you have a lot more freedom with your voltage range. You can run them at lower voltage to produce a cooler vapor or run them up to 6v for a warmer vapor. The closer to 6v you get the more likely you are to run into the burnt taste. Which is where HR/HV comes in.
HR/HV is for a cooler vapor at 6v and warmer above 6v.
Hope that makes sense.
