Internal resistance of a battery cell decreases with:

Internal resistance of a battery cell decreases with:

  • A. an increase in area of the plates inside the electrolyte
  • B. an increase in distance between the two electrodes
  • C. a decrease in size of the electrodes
  • D. an increase of age of the battery

Step-by-step solution

Internal resistance is inversely proportional to the electrode surface area; larger area allows more ions to participate, reducing resistance. Other options increase resistance or do not decrease it.
