Nichrome wire has a high resistance, and that’s exactly what you want in a tool that essentially shorts a battery to make heat. [Techgenie] used a momentary button instead of a switch ...

Anomet Products introduces custom manufactured composite clad metal wire that provides optimum electronics design flexibility by combining multiple properties into a single wire.

This four-wire trick is useful even if you don’t want to measure resistance with precision. For example, high-current or high-accuracy regulated power supplies use the same trick. If your power ...

material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature - heating a wire increases ...
