PURPOSE: To demonstrate that the generator is producing electrical energy, and that the capacitor stores electrical energy.
DESCRIPTION: The generator, the capacitor and the meter are connected in parallel, using the meter as a voltmeter. The capacitor is charged up by cranking the generator. The generator is then run as a motor by energy stored in the capacitor.
See if you can get away with this one: Crank the motor/generator, charging the capacitor. Release the generator handle so that the capacitor causes the motor/generator to rotate. Suggest that a capacitor stores rotation.
SUGGESTIONS:
REFERENCES: (PIRA unknown.)
EQUIPMENT: Genecon generator/motor with 5 volt 1 farad capacitor and lecture-demonstration meter on 5 V scale.
SETUP TIME: 5 min.
