Which term uses chemical paste instead of a liquid electrolyte and cannot be recharged?

• A. Primary/Dry Cell
• B. Secondary Cell
• C. Loads
• D. Semiconductors

Answer: (A)

The concept here is energy storage chemistry and why some batteries can’t be reused. A dry cell uses a paste-like electrolyte instead of a liquid one, making it compact and spill-resistant. This design supports a one-time chemical reaction that cannot be easily reversed by charging, so it isn’t rechargeable. In contrast, a secondary cell is designed to have its reactions reversed by applying electrical current, so it can be recharged. The other terms aren’t about energy storage characteristics: a load is a device that consumes power, and semiconductors are materials used in electronics, not batteries.
