Sine Wave And Rectified Sine Wave
To show the AC output from a generator and how it is converted to full-wave rectified AC using a split ring commutator.
Hand-cranked AC/DC generator with oscilloscope on scope/TV cart.
This uses the large hand-cranked generator and an oscilloscope to actually see the shape of the voltage versus time produced by the generator. It can be used to describe full-wave rectified AC, which can be produced by a rectifier circuit.
