Part 7/9:
In the attempt to induce the electret effect, Paul applied high voltages, incorporating a 1 megaohm resistor and a string of 40 dielectric-rated components, each potentially rated for 1,000 volts. The entire setup was described as very dangerous, emphasizing the importance of safety precautions, as the experiments involved high voltages and the emission of noxious fumes—warnings to those contemplating similar work.
He admits to not having a clear understanding of what constitutes “low DC current” in this context, highlighting the vague instructions that often accompany experimental procedures like these. His notes point to efforts to measure and control electrical input, but unforeseen issues, like sparking and arc jumps, proved insurmountable.
