Why is it important to use 30000 Hz for zapping?
According to research of Dr. Clark when a high frequency ac voltage was applied to a human, using hand electrodes, and the current flow measured, it could be seen that the higher the frequency, the greater the current. At about 30,000 cycles per second the current begins to decline, showing the resistance is increasing. Persons with an inflammation in the body can often feel the zapper at that location, suggesting it is a path of low resistance, too, for the 30 KHz zapper current. Inflamed areas are negatively charged regions. Negative charges would be pulled toward the positive electrode of the zapper in 30,000 little jerks per second. Therefore a frequency of about 30 KHz (30,000 cycles per second) was chosen for the zapper, since it maximizes the current with regular zapping. But other frequencies may prove to have special value as research progresses.
