Q21.76P
Question
Both a D-sized and an AAA-size alkaline battery have an output of V. What property of the cell potential allows this to occur? What is different about these two batteries?
Step-by-Step Solution
Verified Answer
The voltage delivered by a battery remains constant regardless of its size.
The D battery will provide greater current than the AAA battery
1Step 1: Identify the electrochemical problem
Identify half-reactions and species.
2Step 2: Write the half-reactions
Write oxidation and reduction half-reactions.
3Step 3: Apply electrochemical equations
Use E_cell = E_cathode - E_anode or Nernst equation.
4Step 4: State the answer
The answer is:
The voltage delivered by a battery remains constant regardless of its size.
The D battery will provide greater current than the AAA battery
