CHAPTER XIII
THE DYNAMO: BASIC PRINCIPLES
A dynamo is a machine for converting mechanical energy into electrical energy, by means of electromagnetic induction, the amount of electric energy thus obtained depending upon the mechanical energy originally supplied.
The word dynamo is properly applied to a machine which generates[14] direct current, as distinguished from the alternator, which generates alternating current.
Ques. Define a dynamo with respect to its principle of operation.
Ans. A dynamo is a machine for filling and emptying conducting loops with magnetic flux, and utilizing the electromotive force thus induced in them for the production of current in the external circuit.
The fitness of this definition is apparent, having in mind the principles of electromagnetic induction.
Ques. What are the three essential parts of a dynamo?
