DC PRODUCTION USING CHEMICAL CELLS
The conversion of chemical energy into electrical power can be ac-
complished by the use of electrochemical cells. A cell is composed of two dis-
similar metals, which are immersed in a conductive liquid or paste called
an electrolyte. Chemical cells are classified as either primary cells or sec-
ondary cells. Primary cells are ordinarily not usable after a certain period of
