What common household item is an example of chemical energy being converted to electrical energy?

The conversion of chemical energy to electrical energy is exemplified by a battery. A battery stores energy chemically through electrochemical reactions. When connected to an electrical circuit, these chemical reactions release energy in the form of electrical energy, allowing the battery to power devices.

In contrast, options like a light bulb, radio, and fan primarily operate by converting electrical energy into light, sound, or mechanical motion, rather than storing or generating electrical energy through chemical means. Each of these items requires an external source of electrical energy to function, rather than producing that energy internally through a chemical reaction. This distinction highlights the unique role of a battery as a storage device that transforms stored chemical energy into usable electrical energy when needed.
