When I performed my experiment, I made several interesting observations:
- When I had to adjust the space between the wire and foil on each of my lifters, I noticed that the wire tended to be very fidgety, and became easily displaced. While the straws worked fairly well as a means of adjusting the wires without fatiguing them, they were sub-optimal in this respect.
- When the voltage entering my lifters was fairly high, I noted some corona discharge. The corona discharge occurred at a slightly lower voltage if the wire and foil were placed closer together. Corona discharge appeared as a bright blue bolt of light from one area of my lifter which lasted for a fraction of a second, and also a zapping sound. It was occasionally accompanied by a crackling sound and the distinct smell of ozone.
- When my small lifter had a 30mm gap and an input voltage of 21 kV, I noted some wobbling from my lifter, making it challenging to acquire accurate results.
- As I reviewed my results, I noticed that, contrary to popular belief, the deflection of my lifters did not correlate with the voltage, but rather, with the current. I don’t believe this has occurred to anyone thus far.
