Electricity Energy Demonstrator - Dramatically prove that different colors contain different energy potential!
Light emitting diodes, LEDs, convert the energy change of one electron into one light photon. With the Energy of a Photon Demonstrator, slowly increase the energy of the electrons by increasing the voltage across the LEDs and you will see that the red LED comes on at the lowest voltage, then the green, and finally the blue at the highest voltage.
Product comes assembled but you will need your own capacitor and a variable DC power supply. We recommend the Genecon (P6-2631) and our 5V 1 farad capacitor (P6-8012).
