What happens to the amperage when battery cells are connected in series?

When battery cells are connected in series, the total voltage of the system increases while the amperage remains the same as that of an individual cell. In a series connection, the current flows through each cell one after the other; therefore, the same amount of current (amperage) flows through each cell. This means that regardless of how many cells are added in series, the current remains unchanged.

To summarize, in a series configuration, the voltage adds up, resulting in a higher voltage output, but the current stays consistent across the cells. Hence, there is no change in the amperage when batteries are connected in series.
