Heating Element Experiment

view story

http://forum.allaboutcircuits.com – I took a 120v TO 12v dc adaptor which gives 500 mA. I cut the plug, split the wires (exposed copper) and connected them to two nails which have a heating element wire between them. The nails are 7 inches apart. The heating element wire was from a salvaged toaster. The wire won't heat up. Any idea why? Is the current not enough? Regards, Pradhip. S (Embedded)
