Question

a simple cell cannot be used for a very long time.

Answer 1

A cell also called battery consist of an electrode and an electrolyte solution from which electricity is produced.

Primary cell: It is a simple cell that cannot be recharged and can be used only once.

In the primary cell the chemicals are used up for the electrochemical reaction and the reactions cannot be reversed.

So once the chemicals are used up, the battery stops producing electricity.

Thus a simple cell cannot be used for a very long time.
