The product of the mechanical motion is electricity in the dynamo.
The ground carries the electricity back to the dynamo just as a wire would.
But no dynamo ever invented has the power that is centered in the dynamic will of a human being.
The fields of the dynamo are now secured in position to the base.
The positive pole of the dynamo should be connected with the positive pole of the accumulatorp.
In this we have the foundation physical action of the dynamo and the motor.
He cared nothing for the sex of the dynamo until he could measure its energy.
Yet the dynamo, next to the steam-engine, was the most familiar of exhibits.
