Motors and Generators: Coupled Hand-held Generator & Flashlight
Photo of the Demonstration at the University of Texas at Austin.
Instructions / Notes:
- A small hand cranked DC generator is coupled to a second DC generator - which then functions as motor.
- Another, more robust DC generator is connected to one or two automotive light bulbs.
- After about 3 or 4 seconds of cranking, the internal friction of the generator increases due to the resistance of the heated filament in the bulb or bulbs.
- Demo Staff: One of the two, blue Genecon generators needs to be taped to the table top to prevent it from flopping around.
