Query: heating effect of electric current discovery
Useful Output:

Doc 1: When electric current flows through a high-resistance material like the filament in a light bulb, it encounters resistance, causing energy to convert into heat
Doc 2: The more resistance the resistor has, the more heat is produced. This is why electric heaters and iron boxes have different temperature settings.
Doc 3: Who discovered the heating effect of electric current? The heating effect of electric current was discovered by James Prescott Joule.
Doc 4: As this electric effect's name imply, generation of heat due to electric current is known as the heating effect of electricity.
Doc 5: The heating effect of current is described as the generation of heat while an electric current is conducted through a wire.
