Which component converts electrical energy into light and heat?

Explanation:
Electrical energy transforming into light and heat is demonstrated most directly by a light bulb. In an incandescent bulb, current flows through a thin tungsten filament. The filament has resistance, so it heats up until it glows, producing visible light. At the same time, some energy is lost as heat to the surrounding parts of the bulb and environment. A resistor also converts electrical energy into heat, but it isn’t meant to emit light. A battery stores chemical energy to power circuits rather than generating light on its own. A diode can emit light only in special cases like LEDs, and not in the typical sense of a simple light source.
