Question

write the difference between primary and secondary cell ?

Answer 1

Answer:

A primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell(rechargeable battery). ... The energy needed to manufacture a battery is about 50 times greater than the energy it contains.
