PURPOSE: To demonstrate a simple AC/DC generator.
DESCRIPTION: The generator consists of a coil which rotates through an appropriately shaped magnet, which is powered by a 1.5 volt battery. Turning the crank generates either an AC voltage, using a double commutator, or DC voltage, using a split ring commutator. The commutator must be set manually for each case. The output is displayed by a projection meter.
SUGGESTIONS:
REFERENCES: (PIRA 5K40.40)
EQUIPMENT: AC/DC generator with projection meter on overhead projector.
SETUP TIME: None.
