Or how you can get any negative voltage without energy storage. --- End quote --- Just sayin'.... Or just swap the meter probes around... --- End quote --- :) Nice try. You did not changed anything other than the way you interpret the data. I will have a voltmeter at the output of the power supply and one after your circuit with both having the negative probe connected to GND So both voltmeter will measure the same -20V no inversion done by your circuit. --- End quote --- :-DD :palm: :-DD |O |

To convert 20V to 30V, power an LED with 20V. Put enough solar cells in series to produce 30V with the LED powering them. Energy conversion. No energy storage. :=\ Are we back to electrons pushing each other now? |

But as you are interested in electrons will turn this argument around and say the same thing use an LED to illuminate a solar panel and then you may say that energy transfer was done outside the wires through photons. But you did not actually transported electrical energy but you converted to electromagnetic radiation (photons) those traveled through air or vacuum and then were converted back to electricity. Will you accept this as electrical energy travels outside the wires? O will you say energy traveled outside the wire but not as electrical energy? What about the closed loops like the LED and battery? or solar cells and some resistive load? What happens if I put my hand in front of the LED ? Will energy transfer completely stop? How come nothing similar is possible in Derek's experiment? Maybe I should have started by asking what is your position regarding electrical energy transfer. Is it done through wires? or outside the wire? |
