Question

Difference between ➡

⚪⚪⚪⚪PRIMARY CELL and SECONDARY CELL ⚪⚪⚪⚪

Answer 1

primary cell cannot be recharged and secondary cell can be charged.
In primary cell chemical reaction is irreversible and in secondary cell chemical reaction is reversible.
in a primary cell, chemical energy is converted into electrical energy when current is drawn from it and in a secondary cell electric energy is converted into chemical energy when current is passed through it and chemical energy is converted into electrical energy when current is drawn from it.
Hope it helps you
Best of luck

Answer 2

Explanation:

◾A primary cell are of "Single use" that is the cannot be recharged.

◾a secondary cell can be recharged.

◾Secondary cells have a lower capacity and initial voltage generally as compared to primary cells.

◾Secondary cells have the advantage of being more cost-efficient but over the long term as compared to primary cells

◾As individual batteries are more expensive.

◽ In a primary cell chemical reaction is irreversible.

◽In a secondary cell chemical reaction is reversible.

Examples of Primary cells:-

◼ Dry cells and the most alkaline cells.

Examples of secondary cells:-

◼ nickel-cadmium (NiCd), lead acid, and lithium ion cells.
