The correct configuration described, where the positive terminals of batteries are connected to the negative terminals, results in a series configuration. In a series connection, the batteries are lined up one after the other, with the end of one battery connected to the start of the next.

This arrangement increases the total voltage of the system while the overall capacity (measured in amp-hours) remains the same as that of a single battery in the series. For instance, if you connect two 12-volt batteries in series, the total voltage provided by the series configuration would be 24 volts.

In contrast, a parallel connection would involve connecting all positive terminals together and all negative terminals together, which would maintain the same voltage as one battery but increase the capacity. A combination configuration consists of both series and parallel connections, while a grid typically refers to a structured system of interconnected energy sources but does not specifically apply to the direct connection of batteries.

Thus, the direct connection of the positive terminal of one battery to the negative terminal of another creates a series configuration.
