Electrical Engineering - Stymied on how to calculate this


Expert: cleggsan - 12/13/2006

Question
Hi, I wanted to know if you take an acyclic generator homopolar generator (faraday disk high current low voltage generator) and put it in series with a high voltage source, will the current of both the high voltage source and the acyclic generator add together with a resulting average voltage from the two? In this way you could maybe eliminate the high current brush contacts of the acyclic generator. Is this feasible or am I barking up the wrong tree? I'm just not sure how this can be calculated. Thanks

Answer
Nice discussion on the Faraday disc generator at:

http://en.wikipedia.org/wiki/Homopolar_generator

ANSWER:  If generators or connected in series the voltage adds and the current remains the same through the chain.

If the generators are put in parallel the currents will add, theoretically, but the different voltages will not support a direct connection and the differential of the two voltages will cause a fault of some kind; overheating or burning out of the windings, etc.  Even high voltage flash over.

BUT:  It may not be a practical solution because of common grounding or common wiring, etc.  I am not sure how you would connect them in series.  In parallel I think you would be asking for big sparks flying.
