- 1It doubles the available capacity when current is doubled.
- 2It increases the usable capacity by boosting internal chemical reactions.
- 3It decreases the usable capacity due to increased internal I2R losses and polarization.✓
- 4It leaves the total effective capacity unchanged.
Correct answer
It decreases the usable capacity due to increased internal I2R losses and polarization.
