The Heating Effect of Electric Current: A Versatile and Powerful Too l Introduction: The heating effect of electric current is the phenomenon in which an electric current passing through a conductor causes the conductor to heat up. This heating effect is used in a variety of devices, such as toasters, ovens, and electric heaters. The heating effect of electric current was first discovered by Thomas Edison in 1879. Edison found that when a current was passed through a filament of tungsten, the filament heated up and began to glow. This discovery led to the development of the light bulb, which is one of the most common and important devices in the world. The heating effect of electric current is caused by the resistance of the conductor. Resistance is the opposition to the flow of electric current. The higher the resistance, the more heat is generated. The amount of heat generated by an electric current is proportional to the square of the current and the resistance of the conducto...
