PURPOSE: To show the AC output from a generator and how it is converted to full-wave rectified AC using a split ring commutator.

DESCRIPTION: This uses the large hand-cranked generator and an oscilloscope to actually see the shape of the voltage versus time produced by the generator. The double ring commutator puts out AC; the split ring commutator puts out full-wave rectified DC, as seen in the photographs.

SUGGESTIONS:

REFERENCES: (PIRA unknown.)

EQUIPMENT: Hand-cranked AC/DC generator with oscilloscope.

SETUP TIME: 5 min.
