Here's a wierdie; One is always collecting potential on our bodies, frequently called electrostatic voltage. I've found sound research that it is beneficial to "earth" or ground ourselves as often as possible to drain this off. Those last words are the question: does this potential discharge require more than microseconds or perhaps does it ...

A high voltage electrostatic generator operates by converting low-voltage input into stable high-voltage direct current through multi-stage amplification and rectification. This generates a controlled electrostatic field between electrodes. When applied to food preservation, the electrostatic field polarizes water molecules within food ...

The voltage at which this occurs is called the pull-in voltage, Vpi, where A kx V o r o pi 27 ε ε 8 3 = . (2.15) A voltage equal to or greater than Vpi results in an unstable condition where the movable electrode snaps into contact with the fixed electrode. This occurs because the spring force is now always less than the electrostatic force.

Electrode–water interfaces under voltage bias demonstrate anomalous electrostatic and structural properties that are influential in their catalytic and technological applications. Mean-field and empirical models of the electrical double layer (EDL) that forms in response to an applied potential do not capture the heterogeneity that polarizable, liquid-phase water molecules engender.

Charge deposited on the electrode distributes itself through the rod and the gold leaves. Since like charges repel (see demonstration 56.06-- Electrostatically charged rods), the gold leaves, which hang vertically when there is no net charge on them, are now driven apart by electrostatic repulsion, and they splay.
