Part 4/8:
To address this issue, Paul emphasizes the importance of maintaining a flat, tight connection. He describes how he applied tape on the top of the pipe to ensure contact was uniform and experiment with multiple pipes in place. The results were striking—when the pipe was pressed firmly and aligned properly, voltage readings stabilized, confirming the role of mechanical alignment in the experiment.
He also notes that even minor touches or adjustments can cause slight shifts in the measured voltage, reinforcing that mechanical stability is crucial. These insights underscore that electrical experiments are heavily influenced by physical setup, often more than theoretical considerations suggest.
