OHM’S LAW: A BRIEF GUIDE FOR VAPERS

 Vapers who use mods for nicotine vapes have a lot of new terminology to learn. With people throwing out words like watts, ohms, amps and volts as if they’re common knowledge and talking about things like Ohm’s law that you’re lucky if you remember from high school physics, feeling overwhelmed by it all is pretty common. But the good news is that it doesn’t take long to get up to speed with the basics you’ll need to safely and effectively work your mod. So here’s a brief guide to everything you need to know to get started with your VW or mechanical mod.

Vapers often give the advice that “you should learn Ohm’s law before you start vaping with a mod,” but in some cases they don’t really explain why. Ohm’s law tells you the relationships between voltage, current, resistance and power, and so it is central to how vaping works.

The main reason that Ohm’s law is important is working out how much current your coil will draw from the battery. This is important because batteries can only safely provide so much current. This amount of current is called the “maximum continuous current” for the battery, and you need to make sure you stay under this number when you’re vaping. It’s best to avoid drawing the maximum current you’re allowed to, but realistically as long as you stay within the limit you’ll keep vaping safely.

The only extra piece of information you need (which won’t be shown on your mod) is the maximum continuous current of your battery, which you can find through a Google search, on the site you bought it from or other places like Steam Engine (check the drop-down menu beside “battery presets”).

The good news is that while Ohm’s law is important, it’s easy to work out what you need to know, and most regulated mods have plenty of safety features built in to protect you anyway. If you don’t want to do the math yourself, there are plenty of tools to take some of the work away, and as long as you get a capable battery (with a high maximum continuous current), you’ll find you rarely (if ever) have anything to worry about anyway. But it’s better to understand why you don’t have anything to worry about most of the time to walk blindly into a potential problem.
