Which capability does the battery have?

• A. Stores chemical energy and converts it into electrical energy
• B. Stores kinetic energy
• C. Provides magnetic energy
• D. Filters electrical energy

Answer: (A)

A battery’s main capability is to store chemical energy and convert it into electrical energy whenever a circuit is completed. Inside, chemical reactions at the electrodes and in the electrolyte hold energy in chemical bonds. When you connect a load, these reactions drive electrons through the external circuit, delivering electrical energy to power devices. This is what lets a battery store energy for later use. The other ideas don’t describe what a battery does: kinetic energy is about motion, magnetic energy isn’t the primary storage mode for a battery, and filtering electrical energy is what other components like capacitors or filters do.
