Answer:
keep smiling ☺.... and follow me... here is ur answer ...
Explanation:
As electrons move through a metal conductor, some collide with atoms, other electrons or impurities. These collisions cause resistance and generate heat. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance.

If H=V2/ Rt ,then increasing resistance means decreasing the heat produced. But, isnt it that the heat in a circuit is produced due to the presence of resistors? Moreover metals with high resistances are used as heating elements ,like Nichrome? Why does the equation state that the heat produced is inversely proportional to Resistance
