When comparing a Carbon-Zinc cell to an Alkaline-Manganese cell of the same physical size, what is the primary technical reason for the Alkaline cell's superior performance in high-drain applications?

Share:
- 1The Carbon-Zinc cell is a secondary cell and therefore loses charge faster.
- 2The Alkaline cell has a much lower internal resistance and a higher energy density, allowing it to maintain terminal voltage under heavy loads.✓
- 3The Alkaline cell uses a liquid electrolyte that eliminates internal resistance entirely.
- 4The Alkaline cell has a higher open-circuit voltage (1.8 V vs 1.5 V).
Correct answer
The Alkaline cell has a much lower internal resistance and a higher energy density, allowing it to maintain terminal voltage under heavy loads.
