Does anybody think this design has been able to show more energy produced than used?

Short Answer: No! Pepetuum Mobiles never work. And a pulley system does not reduce to work required. It just reduces the force required but at the price of more distance. And since every pulley system ...

Does anybody think this design has been able to show more energy produced than used?

No. The rope has friction. The pulleys have friction. The motor bearings have friction. Bending a rope takes energy. The drawing shows three motors but no generators, so the whole thing is running ...

I've designed a new style of ac alternator where both the stator and the rotor rotate oppsite directions so that rpms multiply by each other

Unfortunately your conjecture that the rpms will multiply is incorrect. The governing equation behind motors and generators (and alternators) is the faraday induction law: https://en.m.wikipedia.org/...

Power Rating of a HV resistor

If I do parse your question correctly, this is what you are trying to do: Test a cap with high AC-Voltages at a fixed RMS current of 0.1A Crank up the voltage until the cap fails Protect your circuit ...

Flyback transformer parameters - Inductance

The best info is already published online by onsemi, TI, and others. I can think of a few fundamentals before I share one onsemi 20-page , how-to select a transformer. Avoid Continuous Mode (CM) even ...

Power loss and voltage drop for a parallel wiring system

If you are only looking at the power consumed by the wire and you know the current that will go through the wires, the power the wires consume = (I^2)*R. However, if you are trying to consume less ...

Is the consumption of a DC motor linear?

The mass of the load doesn't matter, it's the energy expended. If you're moving it downhill, it will take virtually no energy and, with some motors, might give some back. Let's assume you mean "...

How to find the maximum power dissipation or Thermal resistance (J-A)

See section 7. The storage temperature is listed as -65 to 150 C. This might mean that Tjmax is 150 C. But there is no guarantee that it will function correctly at that temp. See note 7-4. The maximum ...
