Which one of the following statements is incorrect:
- A The internal resistance of dry cell is much lower than the common electrolytic cell
- B The internal resistance of dry cell is much higher than the common electrolytic cell.
- C The maximum current that can be drawn from a cell is lower than E/r where E is the emf and r is the internal resistance. E
- D The electrolyte through which a current flows has a finite resistance, called the internal resistance
Answer & Solution
Correct Answer
(A) The internal resistance of dry cell is much lower than the common electrolytic cell
Step-by-step Solution
Detailed explanation
The internal resistance of dry cells (e.g., Leclanché cells) is typically higher than that of common electrolytic cells (e.g., lead-acid cells, which are often referred to as wet cells) due to their paste electrolyte and polarization effects. Therefore, the statement "The…
