Series Circuits: Resistance, Current, and Potential Difference

The video tutorial explores the differences between series and parallel circuits, focusing on how current, potential difference, and resistance behave in series circuits. It explains that in series circuits, current flows through a single path, and the potential difference is divided among components. The total resistance is the sum of individual resistances. Adding more cells increases the total potential difference, while adding resistors increases total resistance.

What happens to the total potential difference when additional cells are added to a series circuit?

Describe how the total resistance in a series circuit is calculated.
