Final answer:
Electric ovens, electric stoves, and light bulbs use resistors as their main component, with these resistors converting electrical energy into heat or light. Batteries do not use resistors; they generate electrical energy through chemical reactions.
Step-by-step explanation:
The devices that take advantage of resistors as the main component are:
- Electric ovens
- Electric stoves
- Light bulbs
Electric ovens and stoves use resistors to convert electrical energy into heat for cooking. An electric stove typically has a coiled resistor on top, known as a heating element, which glows red-hot when electricity flows through it. Similarly, electric ovens contain heating elements that provide the heat needed for baking or broiling. Light bulbs, specifically incandescent bulbs, also utilize resistors. These bulbs work by passing electric current through a thin filament, which acts as a resistor, heating it to a high temperature until it glows and emits light.
Batteries, however, are not based on resistors; they are sources of electrical energy derived from chemical reactions within the battery itself.
