• 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

Answer 1

Answer: (A)

an increase in area of the plates inside the electrolyte

Internal resistance of a battery cell:

1. increases with increase in distance between two electrodes.

2. decreases with increase in concentration of electrolyte.

3. decreases with increase in area of the plates inside the electrolyte.

4. decreases with increase in size of the electrodes.
