It is noticed that durum charging___________?
Correct answer: E. all of the above
- A. there is a rise in voltage
- B. energy is absorbed by the cell
- C. specific gravity of H2SO4 is increased
- D. the anode becomes chocolate brown in colour (PbCfe) and cathode becomes grey metallic lead (Pb)
- E. all of the above
Explanation
During charging, electrical energy is stored chemically, the terminal voltage and electrolyte specific gravity rise, and lead sulfate changes into brown lead dioxide at the positive plate and grey lead at the negative plate. Therefore, all listed effects occur.
