Heating coils with a 9v, why doesn't this work?

[KB971033]

Before I say anything I want to say I'm extremely new to electronics.
So I've ordered a spool of nichrome but in the meantime I've seen a lot of videos using small coils made from twist ties being used to make small lighters. Some videos have special batteries but a lot of them just use AA's or consumer 9v's to power the devices. I've made a small coil from a twist tie and I'm using a 9v battery and even when I touch the leads of the coil directly to the terminals on the battery I still get almost no heat whatsoever. If I attach the coil to my power supply(19amps 13.8volts, I realized this was an extremely poor choice as soon as the unit shut it's self off...) it glows bright red and starts to lose its shape like I expected. This leads me to believe that I'm just lacking amperage when I use the 9v and I'm wondering if the only thing I can do to rectify this is use nichrome or if I'm missing something? The videos all have little to no explanation they just have music and it's wildly frustrating.

Notes:
I can't check the resistance of the coil, my multimeter is broken.
I also tried it with a set of 8 AA's wired in series with the same negligible amount of heat

Try doing some basic electrical/electronics 101 as you have no understanding.
I'm sure there are millions of sites on Google.
What you are attempting is just a dead short.

Here's an explanation of the issues you encounter.

Actually, you should be able to get some heat from a 9V battery for a short period of time. A fresh one should be able to supply about 1A, but only for minutes. What size of nichrome wire did you buy? You would want a fairly fine one.

I think your shorted battery will produce more heat than your nichrome wire or twist tie. But only a brand new alkaline battery and only for a minute or two.

I forgot to say that a new 9V alkaline battery will heat itself to about 12W for a few seconds when shorted then it will be dead in about 2 minutes. It takes time to heat up and the amount of internal heat will be dropping all the time it is shorted. Your power supply produced 19A x 13.8V= 262.2W continuously to your twist tie coil which is 22 times more power than the little 9V battery.

Maximum power output will be when the source resistance equals the load resistance. The heating in the battery and load will be the same. Treating a battery like this however will give a it very short life.

28 gauge, I also bought some 18650 batteries because I've seen this done with them as well. Would those provide a more impressive result?

Why not look up "how to make a VAPE thingy".

 

[BobK]

18650's are capable of much more current than a 9V, but are at a lower voltage.

Here are some nice charts about Nichrome wire:

Nichrome wire

28 gauge wire is about 4Ω per foot, and it takes almost 3A to heat to 1200 F which is what you would need to be "red hot". Less if you coil it. A nine-volt is not going to do that.

You would need a finer wire to heat to red hot with a nine volt.

36ga is 26Ω per foot. You If you used about 6 in in a coil that might do it.

Unfortunately, YouTube videos often show things that look neat but aren't possible in this universe - mostly, they're fake, Just trying to get "views".
