Internal resistance of a cell is due to___________?
Correct answer: D. all above
- A. resistance of electrolyte
- B. electrode resistance
- C. surface contact resistance between electrode and electrolyte
- D. all above
Explanation
Cell internal resistance includes ionic resistance of the electrolyte, resistance of the electrodes, and contact or polarization resistance at the electrode-electrolyte interfaces. These components combine to give the cell's effective internal resistance.
