Question

Which of the following statement(s) is/are correct about a dry cell?

• A. Zinc acts as the negative terminal of the cell.
• B. It can be recharged once its contents are exhausted.
• C. A carbon rod with a metal cap acts as the positive terminal.
• D. It contains a mixture of aluminium chloride and carbon particles.

Answer 1

Answer: (A), (C)

The correct options are
A Zinc acts as the negative terminal of the cell.
C A carbon rod with a metal cap acts as the positive terminal.

A dry cell contains a container made of zinc acting as the negative terminal and a carbon (graphite) rod with a metal cap acting as the positive terminal. A mixture of carbon particles and ammonium chloride is present between the positive and negative terminals. Once the chemical contents of the cell are exhausted, it stops producing electricity. These contents are not regenerated when electricity is supplied from external sources. Hence, the cell cannot be reused or recharged.
