Despite the undesirability of heat generation in electric circuits, the heating effect of electric current is intentionally utilized in various devices. Electric heaters, soldering irons, and stoves rely on controlled heating through resistive elements. Incandescent light bulbs exploit Joule’s heating to produce light. Hairdryers and toasters use this effect for specific functions. In electric blankets, wires generate heat for warming. The deliberate application of the heating effect allows for the design of devices serving purposes such as cooking, illumination, climate control, and more. However, energy-efficient technologies increasingly prioritize minimizing heat generation, as it represents energy loss in many electronic applications.
