What device converts chemical energy to electrical energy?

• A. Generator
• B. Battery
• C. Solar panel
• D. Transformer

Answer: (B)

The device that converts chemical energy to electrical energy is the battery. A battery works through electrochemical reactions, which involve the transformation of chemical energy stored in the materials within the battery into electrical energy. This process occurs in the battery’s electrochemical cells, where a chemical reaction generates a flow of electrons, leading to an electric current that can be used to power devices or charge other batteries.

In contrast, a generator primarily converts mechanical energy into electrical energy, often using kinetic movement to generate power. A solar panel converts solar energy (light energy) directly into electrical energy through the photovoltaic effect, while a transformer is used to change the voltage of electrical energy but does not convert one form of energy to another. Thus, the battery is specifically designed for the purpose of storing and converting chemical energy into electrical energy, making it the correct answer.
