A common everyday representation of chemical source of electricity is?

The correct choice is a battery, which is a device that stores electrical energy in the form of chemical energy. It generates electricity through electrochemical reactions that occur within its cells. When the battery is connected to a circuit, these chemical reactions produce a flow of electrons, creating an electric current. This process is fundamental in many everyday applications, such as in powering devices like remote controls, flashlights, and smartphones.

In contrast, while a solar panel converts light energy into electrical energy, and a generator usually converts mechanical energy into electrical energy, neither directly relies on chemical reactions. A capacitor is used to store electrical energy briefly and release it quickly, but it does not generate electricity through chemical processes. Therefore, a battery stands out as the most common and recognizable example of a chemical source of electricity.
