Question

What is a primary cell? Name two such cells.

ICSE Class 9 Physics Chapter Current Electricity

Answer 1

A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering thecell unrechargeable.

Answer 2

Primary cells are those which cannot be recharged i.e. they become dead after some time and they cannot be used again.

For example: the primary cells  are used in watches, calculators etc.
