Question

which type of energy is stored in a battery?

a. nuclear energy

b. electrical energy

c. chemical energy

d. electromagnetic energy

Explanation:

• Option A: Nuclear energy is related to atomic nuclei (e.g., in nuclear reactors), not batteries.
• Option B: Electrical energy is the energy of moving charges; batteries store energy to produce electricity later, not store electrical energy directly.
• Option C: Batteries use chemical reactions (e.g., in electrochemical cells) to store energy as chemical energy, which is converted to electrical energy when used.
• Option D: Electromagnetic energy includes light, radio waves, etc., not the energy stored in batteries.

Answer:

C. Chemical energy
