**Potential Difference from Batteries**

In this lesson, we will

• Explain what is meant by a battery.

• Calculate the potential difference from a battery, based on the direction of the cells.

When two or more cells are connected in series in a circuit, the total potential difference is the sum of their potential differences. If two cells with the same potential difference are connected in series, but in opposite directions, the total potential difference is 0 V, so no current will flow.
