"WebMar 16, 2024 · This is known as Joule's law of heating. The law implies that the heat produced in a resistor is directly proportional to the square of current for a given resistance It means if we double the current,the heat becomes 4 times if we half the current,the heat becomes 1/4 times Hence,more the current,more the heat. Less the current, less heat … " - State joule's law of heating
