The effect of sulphation is that the internal resistance__________?
Correct answer: A. increases
- A. increases
- B. decreases
- C. remains same
- D. none of the above
Explanation
Sulphation forms hard lead-sulphate deposits on the plates, reducing the effective active area and hindering chemical action. Consequently, the cell's internal resistance increases.
