Difference Between Primary Cell and Secondary Cell

In this topic, you study the Difference Between Primary Cell and Secondary Cell.

The differences between the primary and secondary cells as :

Primary cell

1. The e.m,f. is induced as soon as its components are assembled.
2. If discharged cannot be recharged again.
3. It cannot work continuously for long time,
4. These are light in weight.
5. The life is short.
6. It has higher intemal resistance.
7. These are Voltaic, Lachlanche, Dry, Bunsen, Danial, Bichromate, Standard cell,

Secondary cell

1. The e.m.f. and current is available if it is charged.
2. If discharged can be recharged again with its old components.
3. It can work continuously for a long time.
4. They are heavy.
5. It has long life.
6. The internal resistance is comparatively low.
7. These are lead acid cells, NiFe cells, NiCd cells.
