Updated On: Feb 3, 2026
- spongy lead
- lead peroxide
- dilute H2SO4
- all of these
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Components of a lead acid cell.
The active materials in a lead-acid cell include spongy lead (Pb) on the negative plate, lead peroxide (PbO₂) on the positive plate, and sulfuric acid (H₂SO₄) as the electrolyte.
Step 2: Conclusion.
Thus, all the given materials are part of a lead-acid cell, corresponding to option (D).
