Understanding Ohms Law V=IR is a requirement?

Not really. It does help a lot with vaping in general though.

It's kind of a bummer in a way. Sometimes I think we all (myself included) go overboard with this vaping electronics stuff. But we ARE messing with electricity. And the more options you have, the more types of mods you use, the more you will want to understand the "whys" of things.

If you just stay in standard ohm ranges, and know what batteries to use....probably not a big issue. But if you want to know WHY it gets hotter with lower ohms, or check the safety limits and amp draw when vaping low ohms, or understand how the resistance in a mod will affect the coil's heat....yeah, you need to understand it.

You can stay with a cig-a-like or even an eGo-a-like and just know what ohm coils to buy. Meh.

Kanger EVOD 650mAh Starter Kit I haven't got a chance of understanding Ohms Law V=IR.

Don't freak out. You don't HAVE to understand it. (But you have more chance than you think.)

Just know that lower ohms = hotter coil and faster battery use. Stay in the 1.8 to 2.2 ohm range for that. That's all you need to know.

Considering the available mods and variable voltage/wattage devices that are out there. A basic understanding of Ohms Law can't hurt. If you want over power your coils...have at it. But I still believe that one should know about what they are doing before they do it.

Did you smoke before vaping?

Were you a cardiologist, pulmonologist, tobacco grower, or expert in combustion?

Besides, we don't want to scare people away. That's mega counter productive. So we have to deal with this issue in context....
Like using mech mods. Or building your own coils. That kind of specifics.

It can't hurt to know it. I've encouraged people to learn more about the electrical part for years here on ECF. But don't scare em. Put it in context.

It's really not that hard to understand. The math only comes into play when you start using mods or VV's (Variable Voltage devices). The whole idea is to find a perfect power rating for the best vape possible. Some think higher voltage, some think higher current. I think it's a matter of preference. But the common theme is to understand the math. Voltage = Current x Resistance.

Just my :2c:

Yes, I am an ex-smoker. I am not any of those things you asked about. Just a simple Electrician who understands Ohms Law. I wasn't trying to scare anyone away. I was simply pointing out that knowing Ohms Law was a good thing to know.

Good recommendation. Those Sears meters are made by Extech and are better made than the horrible cheap Harbor Freight meters I see mentioned too often.

Learned that lesson the hard way... twice. Yeah, it was stupid of me to think it was a fluke that the first one crapped out on me so quickly, then to buy another one (died just as quickly). I'll have to stop by sears sometime soon.

And you're absolutely right!

I'm not beating on you.

However, we need to understand that everyone/anyone on the net reads these posts. So we need context. We were "scaring" darkcelestialillumination who is using an Evod with pre-made heads and doesn't want to know ohms law (yet).


Agreed.

Dark, Stick with you kit. The important thing is that you quit smoking cigarettes. When you're ready to upgrade, help is here on the forum.

When it matters, buy the best. I would never trust anything from china-freight!!!!!!!

Thanks for the link to the Sears meter. I was just looking for my old ratshack meter that I have had for ages, but I can't seem to find it. Sears is already closed tonight but I will be there first thing tomorrow morning. Looks pretty sweet for $10!
You are welcome!

That's about all I would like to do. Hope that everyone can take advantage of the sale.

Cheers
