🔍 Key Concepts

• Construction of a standard dry cell (Leclanché cell) • Which material serves as the container and negative electrode • Which material serves as the central rod and positive electrode

💭 Think About

• Think about what metal the outer can of a common flashlight battery is usually made of and what its electrical role is. • Consider what the central rod inside the paste of the battery is made of and whether it is connected to the positive or negative terminal. • Ask yourself: in a typical dry cell, is the metal can the positive or negative side, and is the carbon rod the positive or negative side?

✅ Before You Answer

• Be clear which part is the zinc can and which part is the carbon rod. • Confirm which part is connected to the positive terminal (button end) and which to the negative terminal (flat can end). • Verify whether both statement A and statement B correctly describe the usual dry cell construction before considering choice D.
