SUMMARY
The discussion centers on the relationship between resistance and heat in electrical circuits, specifically highlighting that alloys exhibit higher resistivity than pure metals. The formula H=V^2/R demonstrates that resistance is inversely proportional to heat generation. Consequently, alloys produce less heat due to their lower resistances when a constant voltage is applied. This results in greater power dissipation under low resistance conditions.
