Thinking more about it now I do want to err on the side of not killing
my terrarium inhabitants. So a wall wort transformer is the way to go.
the purpose of using wire and a resistor is so the wire can be sealed
in silicone tubing for fish tanks and siliconed on the ends., it just
seems easier to seal up. what theory do I need to apply to heat up say
4 feet of wire not just the resistor?



Okay so I now know how to come up with the length of wire and
transformer. If I wanted to use a long wire and coil it, do the coils
absolutely have to not touch? What if they do? I believe a smaller wire
that is longer and coiled will give me a more pliable cable.

Ok, i don't know if this falls within the realm of electronics but you
guys may be able to point me in the right direction. Is there a formula
to determine the amount of heat coming off of on eof these cables?


What unit of measure do you think you'd like to see? If I say 15
Joules will that make sense? If I say 15 watts then how about that?
Or, are you interested in temperature rise? Or BTUs? Or Calories?

There are so many ways of saying that!
