Which of the following is a device used to convert chemical energy into electrical energy?

A battery is indeed a device that converts chemical energy into electrical energy. This process occurs within the battery as it undergoes a chemical reaction, allowing it to generate an electric current. When a battery is connected to a circuit, the chemical reactions inside rearrange the components and release electrons, which flow through the circuit, providing electrical power.

Understanding how batteries work is crucial, especially in applications where portable or stationary power sources are needed. In contrast, other options serve different purposes. An alternator converts mechanical energy into electrical energy, a solar cell transforms light energy into electrical energy, and a wind turbine converts kinetic energy from wind into electrical energy. Each of these devices relies on different energy sources, underscoring the unique role that batteries play in energy conversion.
