Beginners coil building resistance explanation

[bobby00]

Hi
I just found this on YT and it really helped me to understand more about how to build coils and what the resistance factor is?



In a nutshell a dead straight piece of wire has low resistance and the longer it gets ie more wraps the higher the resistance gets!
very simplistic but it explained it a bit more "The lower the resistance = less Ohms the higher the resistance the more Ohms"
which would also I assume need more power to heat it up?

I am a complete novice so if I'm wrong do correct me please?

Mostly right, well done, just the "I assume need more power to heat it up" that is not accurate.

Higher res would need more voltage to get up to power/heat, but power is independent of resistance really (technically electrical power in watts derives from heating power or Joule heating of a resistor used forever to rate toasters, light bulbs Etc. and you never worried what their resistance was)

There is a lot of BS confusion still being spread from when unregulated/fixed-voltage/variable-voltage devices were more popular and we only used Nichrome and Kanthal wires, but since variable wattage came in 2010 it's all far far easier: just set the power and vape. Unfortunately these rules about res and power linger and get applied to the mainstream VW vaping world like the nonsense phrase sub-ohming, res is not completely unimportant, just not nearly as important as it is usually made out to be. Don't sweet it all you really need to do is make sure you are in the range your mod supports if you are using VW or VV, mech and fixed voltage are different and res determines the power.
