WebJul 17, 2011 · This implies that the relationship between temperature and electric current is universal for CE, or at least for all CE cooled by the same method (a fan in this case). Subsequent research has revealed that cooling CE by forced air causes the temperature to rise at a slower rate, producing a line with a slope of 4.0°C m/W.

Web\$\begingroup\$ There is no relationship between resistivity and heat.There is a relationship between resistivity, and the ease with which you can, with common tools, cause something to produce a lot of heat.However, this relationship is purely one based in the limitations of common lab tools. WebThe heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat. The time, t for which current flows. The longer the time the larger the amount of heat produced. The amount of current, I. the higher the current the larger the amount of heat generated.
