What is another name for a "primary cell" used in electricity?

A primary cell is a type of electrochemical cell that is designed for single-use and cannot be recharged once depleted. It generates electrical energy through irreversible chemical reactions. The term "dry cell" is a common name for a type of primary cell, which typically contains a paste or gel-like electrolyte rather than a liquid, making it more portable and leak-proof.

Dry cells are widely used in everyday batteries, such as those found in flashlights and remote controls. Their design allows them to be compact and convenient for a variety of applications, contributing to their popularity. This understanding of what constitutes a primary cell correlates well with the definition of a dry cell, affirming why this choice is considered the correct answer.

In contrast, other options refer to different types of cells or systems. Wet cells contain liquid electrolytes and are used in situations where higher power is needed but are less practical for portable devices. Rechargeable cells are specifically designed to be reused through recharging, thus differing fundamentally from primary cells. The term "super cell" does not correspond to an established category of batteries or cells within electrical engineering, further distinguishing it from the designation of a primary cell.
