Vintage Welch Scientific Series-Parallel Electric Trainer Demonstrator 5 Light
This listing is for a vintage Welch Scientific Series-Parallel Electric Demonstrator.  The display can be set up to show how a parallel wired circuit and a series wired circuit are different and what the results are by the brightness of the bulbs.  The unit needs to be connected to a power source. (Not included.) This was made to work with standard household lightbulbs so it most likely was wired up with a standard electrical plug. (Not exactly kid friendly!)
