===== Description =====
Demonstrates resistance of a metal varying with temperature
===== Purpose =====
To show that the resistance of a metal decreases when cooled; this demonstrates a positive temperature coefficient of resistance.
===== Apparatus =====
Dewar flask, liquid nitrogen, light and series wound resistor
===== Setup =====
1. Switch on apparatus and since the resistor is in series with the lamp and the 115 V supply for the lamp will not glow at full brightness.
2. Dip resistor into the liquid nitrogen and the light will shine brighter. Updated on: 01/18/16
