Question:
The negative plates of a lead acid battery have
The negative plates of a lead acid battery have
Show Hint
Understanding the chemistry of lead-acid batteries, including the materials of the plates and their reactions, can aid in troubleshooting and improving battery life and performance.
Updated On: June 02, 2025
- Lead peroxide (PbO_2)
- Spongy lead (Pb)
- Lead sulphate (PbSO_4)
- Lead Hydrate (PbH)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The negative plates of a lead-acid battery are made from spongy lead. During the battery's discharge cycle, the spongy lead (Pb) reacts with the sulphuric acid electrolyte, forming lead sulphate (PbSO$_4$), while the positive plates, made of lead dioxide (PbO$_2$), undergo a similar transformation.

- An intermediate shaft of a gearbox, supporting two spur gears A and B and mounted between two bearings C1 and C2, is shown in the below figure. The pitch circle diameters of gears A and B are 500 and 250 mm respectively. The shaft is made of alloy steel 20MnCr5. (\( S_{ut} = 620 \) and \( S_{yt} = 480 \) N/mm\(^2\)). The factors \( k_b \) and \( k_t \) of the ASME code are 2 and 1.5 respectively. The gears are keyed to the shaft. Determine the shaft diameter using the ASME code.
