In this middle-school friendly demo, we use the PhET Circuit Construction Kit (DC) to compare series and parallel connections with three bulbs and dry cells. Watch how adding cells in series increases total voltage and brightness, why the same current flows through all series bulbs, and how a fused bulb turns them all off.
