For cells connected in parallel, which statement is correct?

• A. Voltage increases, capacity increases
• B. Voltage increases, capacity remains the same
• C. Voltage remains the same, capacity increases
• D. Voltage and capacity both remain the same

Answer: (C)

When cells are connected in parallel, they share the same voltage across all the cells. This means the overall voltage of the setup does not increase; it remains constant and is equal to the voltage of a single cell. However, one significant advantage of connecting cells in parallel is that the capacity (also known as amp-hour rating) increases. Each cell contributes its capacity to the total capacity of the parallel configuration. This allows the system to store more energy, making it beneficial for applications that require a longer duration of power supply while maintaining the same voltage level. When cells are connected in parallel, they effectively add their capacities together while keeping the voltage level consistent. This characteristic makes parallel connections particularly useful in various applications, such as in battery systems and power banks, where increased capacity without increased voltage is desired.
