About This Product
Turning the handle moves a coil through a magnetic field and induces an emf, which demonstrates Faraday’s law and the change of mechanical work into electrical energy. Swapping the slip-ring armature for the commutator armature lets students see a current that reverses direction become a pulsating one-way current, and compare how the two generators are built. Educational Instrument can dispatch the Dynamo Model AC DC to laboratories in Chad, Palestine, Vanuatu, Argentina, Eswatini and Gabon.
Frequently Asked Questions
How does the model produce both AC and DC?
It is supplied with two armatures: a slip-ring armature for alternating current and a commutator (split-ring) armature for direct current.
Is a meter included with the Dynamo Model AC DC?
The source does not list one. The output is monitored with an external device such as a galvanometer or oscilloscope.
