Part 3/5:
An essential component of their experiments involved using a 60 Hz psycho power source to modulate the system's voltage. A video capturing the system's operation demonstrates the diverse sounds produced by the arc—an auditory window into the dynamic electrical activity occurring within. The systems used include an adjustable AC voltage supply, approximately 200 volts, to power the carbon arcs.
The modulation of AC voltage introduces a variety of visual and acoustic effects, making the system especially fascinating. These variations in power not only influence the colors and shapes but also create an array of interesting phenomena, as demonstrated in the clips and photos captured.
