Primary cells are batteries that are not easily recharged after use, while secondary cells are those which can be recharged. Usually, primary cells are discarded

Primary cells are the ones which are discarded after using it to its full capacity. They can't be recharged. Secondary cells can be recharged and used again.

primary cells are cells which cannot be recharged, once the electrolyte is used up and the emf goes down, you have to replace it, eg:dry cell Secondary cells are cells which can be used again and again by recharging it.eg: lead acid accumulator,lithium cells

Primary Secondary 1)Lower initial cost. Higher initial cost. 2)Higher life-cycle cost ($/kWh) Lower life-cycle cost ($/kWh) if charging in convenient and inexpensive. 3)Disposable. Regular maintenance required. 4)Disposable. Periodic recharging required 5)Typically lighter and smaller; Traditionally less suited for portable applications, thus traditionally more suited although recent advances in Lithium battery technology for portable applications. have lead to the development of smaller/lighter secondary batteries. 6)Longer service per charge Traditional secondary batteries (particularly aqueous secondary batteries) and good charge retention. exhibit inferior charge retention. 7)Traditionally limited The overall inherent versatility of secondary battery systems allows its use to specific applications. and continuing research for a large spectrum of applications. read less

__________ of the following is not a fundamental postulate of Bohr’s theory of hydrogen atom. (The total energy of the electron in one of it allowed orbit remains constant as long as it remains in the same orbit, An electron can not revolve in an arbitrary orbit. Only those orbits are possible for which the angular momentum of the electron about the nucleus is an integral multiple of h/2p, The electron can move in all possible orbits, An atom radiates energy only when an electron jumps from an allowed orbit of higher energy En to one of the lower energy Ep)
