Inspired by my physics class, I wanted to build a perpetuum mobile, where electrons keep travelling through a conductive loop. As my experiments were not successful, I looked for other applications of my apparatus. I realized that the effects of electrical fields would not cancel for an interrupted conductive loop.
The resulting capacitive voltage converter follows the relationship U1/U2 = d1/d2.
After my theoretical analysis, I built a double capacitor. However, I noticed quickly that it was not rolled tightly enough as the voltage U2 was too small. Therefore, I built a new capacitive voltage converter which I pressed. This resulted in a larger voltage U2 that was consistent with theory. However, my capacitive voltage converter is only suitable for devices that use little energy, e.g. calculators, diodes or watches.
