Will more voltage be available when individual cells of a battery are connected in parallel?

• A. True
• B. False
• C. Depends on the cells
• D. Only if they're identical

Answer: (B)

When individual cells of a battery are connected in parallel, the voltage across the terminals remains the same as the voltage of a single cell, rather than increasing. This is because, in a parallel configuration, each cell is connected directly to the same voltage source, and as such, they maintain the same potential difference across them. Therefore, while connecting cells in parallel increases the overall capacity (measured in amp-hours) of the battery system, it does not increase the voltage. In contrast, connecting cells in series is what increases the voltage; each cell's voltage adds to the total. Thus, the answer about whether more voltage will be available when cells are connected in parallel is indeed false.
