Hello all...
I have been having some trouble with some nickel/chromium resistance wire I have brought to act as a heating element, it is 0.375mm dia. and I am using 100mm lengths. I had originally intended to heat it up with a standard 9V battery, but it is behaving strangely when I connect it to the +ive & -ive terminals. It seems to heat up very quickly at first, as it should, and then stop heating and cool down after the first few seconds. It is definitely not flattening the battery, becuase if I wait a while and try again, the same thing happens.
Is this something to do with it shorting the battery, and is it even possible to heat wire like this with a 9V battery, ideally so it glows red. (I am trying to make a cigarrette lighter)
Apologies if this is a stupid question, electricity really is not my strong point :)
