In a battery bank, if the positive terminals are connected, what configuration results?

Short circuit
Series
Parallel
Open circuit

The correct answer is: Short circuit

When the positive terminals of a battery bank are connected together, this configuration results in a parallel connection. In a parallel setup, the positive terminals of each battery are interconnected, and the same goes for the negative terminals. This means that all batteries share the same voltage while their capacities (amp-hours) add up. In contrast, a short circuit occurs when there is a direct connection between the positive and negative terminals of a power source without any load. This creates a path with very low resistance that can lead to excessive current flow, potentially damaging the batteries. Thus, connecting the positive terminals alone does not produce a short circuit but instead allows for a parallel configuration that enhances the overall charge capacity of the battery bank while maintaining the same voltage. Understanding this distinction is crucial for proper battery bank setup and management in recreational vehicle applications.
