Which one of the following statements is incorrect: |
The internal resistance of dry cell is much lower than the common electrolytic cell The internal resistance of dry cell is much higher than the common electrolytic cell. The maximum current that can be drawn from a cell is lower than $\frac{E}{r}$, where E is the emf and r is the internal resistance. The electrolyte through which a current flows has a finite resistance, called the internal resistance. |
The electrolyte through which a current flows has a finite resistance, called the internal resistance. |
The correct answer is Option (4) → The electrolyte through which a current flows has a finite resistance, called the internal resistance. Dry cells are primarily cells, which are single used batteries that are disposed of after chemicals are used up. They have high internal resistance to complete the internal resistance to complete the internal reactions that used up the chemicals. |
