Which term refers to a device that stores and releases energy electrochemically?

• A. Conductor
• B. Battery
• C. Inverter
• D. Rectifier

Answer: (B)

Storing and releasing energy electrochemically describes a battery. It uses chemical reactions at the electrodes separated by an electrolyte to store energy as chemical energy. When the circuit is closed, those reactions drive electrons through the external path, delivering electrical energy to the load. When charging, external energy pushes the reactions in the reverse direction, restoring stored chemical energy for later use. This is different from a conductor, which merely conducts current without storing energy; an inverter, which converts DC to AC; or a rectifier, which converts AC to DC. So the term that fits is battery.
