PS: Resistors have a POSITIVE temperature Coefficient; meaning that the hotter it gets, the more resistance it has. Resistors, and ALL conductors have this 1/1 Proportional temp/ohm ratio. Semiconductors, like Silicon, Germanium, (Used in transistors and Diodes,) Have a NEGATIVE temperature coefficeint; meaning that the hotter it gets, the lower the resistance. That's called a cascade, or Avalanche.
