(3) Lead/ सीसा (4) Zinc/ जस्ता
Answer / उत्तर :-
(3) Lead/ सीसा
Explanation / व्याख्या :-
The electrodes of the cells in a storage battery consist of lead grids. The openings of the anodic grid is filled with spongy (porous) lead. The openings of the cathodic grid is filled with lead dioxide (PbO2). Dilute sulfuric acid (H2SO4) serves as the electrolyte.Leadacid batteries, also known as lead storage batteries, can store a lot of charge and provide high current for short periods of time./ The electrodes of the cells in a storage battery consist of lead grids.
