Circuit Rules: Series and Parallel Circuits

The video tutorial covers the basics of series and parallel circuits, explaining the rules and calculations associated with each. In a series circuit, components are connected sequentially, sharing the same current, and the total resistance is the sum of individual resistances. An example is provided to calculate total resistance, current, and potential differences. In parallel circuits, components are connected in branches, sharing the same potential difference, and the total resistance decreases as more branches are added. Another example demonstrates calculating current and resistance in a parallel circuit.
