Which type of energy is primarily stored in a battery?

• A. Chemical energy
• B. Nuclear energy
• C. Thermal energy
• D. Kinetic energy

Answer: (A)

Verified step by step guidance

1. Understand that a battery stores energy in a form that can be converted into electrical energy to do work.
2. Recall the types of energy: nuclear energy involves changes in the nucleus, thermal energy relates to heat, kinetic energy is energy of motion, and chemical energy is stored in the bonds of molecules.
3. Recognize that in a battery, energy is stored in the chemical bonds of the substances inside it, which release energy through chemical reactions.
4. Therefore, the primary type of energy stored in a battery is chemical energy.
5. This chemical energy is converted into electrical energy when the battery is connected in a circuit.
