Purpose:Demonstrate combinations of series and parallel light bulbs.
Description:This demonstration consists of a series of 5 bulbs and a power supply that can be connected in various combinations. The top surface is illustrated with black lines showing the internal connections, which can be wired in various series/parallel combinations as desired by removing and replacing small shorting bars to complete the circuit. After wiring, the device is connected to 110 VAC power, the switch is turned on, and bulbs should light. Check for shorts!
The photographs above show all of the lights in parallel (top) and all in series (bottom).
