The extent of charge of lead accumulator is determined by
- A amount of \(\mathrm{PbSO}_4\) in the battery
- B amount of \(\mathrm{PbO}_2\) in the battery
- C specific gravity of \(\mathrm{H}_2 \mathrm{SO}_4\) of the battery
- D amount of \(\mathrm{Pb}\) in the battery
Answer & Solution
Correct Answer
(C) specific gravity of \(\mathrm{H}_2 \mathrm{SO}_4\) of the battery
Step-by-step Solution
Detailed explanation
In a fully charged lead accumulator or lead storage battery, sulphuric acid has a specific gravity (i.e., density that varies from 1.260 to 1.285. But during discharge (i.e., when the battery is in use). \(\mathrm{H}_2 \mathrm{SO}_4\) is used up.…
