What is the negative electrode typically made of in a usual type dry cell?

• A. The negative electrode is made of zinc
• B. The positive electrode is made of carbon
• C. The negative electrode is made of copper
• D. The positive electrode is made of magnesium

Answer: (A)

The negative electrode in a typical dry cell is made of zinc. In the conventional structure of a dry cell, the zinc serves as the anode, which is where oxidation occurs during the electrochemical reaction. This reaction generates electrons that flow through the external circuit to the positive terminal, creating an electric current. Understanding this component is crucial, as it plays a vital role in the overall functioning of the battery. The interaction between the zinc negative electrode and the electrolyte allows the chemical energy stored within the cell to be converted into electrical energy for various applications. In contrast, the other options mention materials that are not used as the negative electrode in a standard dry cell arrangement. Carbon is commonly used for the positive electrode, serving as the cathode, while copper and magnesium are not typical materials found in the standard dry cell configuration. Copper can be found in other types of batteries, but it does not function as the negative electrode in this context.
