Series and Parallel Light Bulbs

The demonstration illustrates how bulbs behave when connected in series and in parallel. In the setup, as seen in the attached image, there are five light bulbs mounted in holders, connected by removable aluminum wire pieces. When the bulbs are connected in series, the same current flows through each bulb, but the voltage is divided among them. This results in dimmer bulbs as more bulbs are added, due to the increased total resistance and the lower voltage across each bulb. In a parallel configuration, each bulb receives the same voltage, so they maintain consistent brightness, regardless of how many bulbs are connected. However, the current drawn from the power supply increases as more bulbs are added in parallel, since the total resistance decreases. This demonstration visually contrasts the behavior of current and voltage in series versus parallel circuits and provides insight into how electrical loads interact in different configurations.
