Description

Generates both AC and DC. When the two brushes of the generator are put in the two ends of the commutator, the output is an AC. When the brushes are put in the middle of the commutator, the output is a DC. Includes Instructions.

Description

The large size of this battery operated apparatus allows students to better understand the operation of this basic circuit. Works on 9 V Battery. Includes Instructions. On wooden stand.

Description

The dynamo model is mounted on a base with a driving wheel. Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.
