To easily understand Joule’s Law, we must first understand the concept of electrical resistance.
A resistance is the physical component that transforms electrical energy into heat energy, this due to the shock generated by the electron conductive material of said resistor, thereby generating heat energy.
Electrical Resistances. (For more detail of resistance)
Joule’s law can determine the amount of energy (electricity) as heat dissipation due to atomic collisions as described above. This amount of heat depends on the current that flows through the resistance and the time that is connected.
