However, a super-high TC would mean electrical resistance (which is also very important for a variety of applications, like heating) would be similarly difficult to ascertain. “The wire would ...

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 ...

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 ...
