No heat from nichrome wire. I have tried various experiments on YouTube regarding foam cutters using nichrome wire or steel wire with 9V batteries with an on/off switch or no on/off switch.
When the steel wire didn't work, I tried using N80 30AWG nichrome wire. I connected the wires from the battery directly to the nichrome wire and no heat at all. I even tried connecting two 9V batteries. I only have a basic understanding of electricity but the simple DIY foam cutters on YouTube do not seem to be much of a challenge to create. Appreciate any help or other tests I can perform to confirm I am getting heat. Oh and the batteries are fully charged.
