What is a Zapper?
A “zapper” is defined by Dr. Hulda Clark as a battery operated DC pulse (positive offset) generator with an output amplitude of 5 to 10 volts (open circuit) and a frequency between 10 Hz and 500KHz (10 to 500,000 pulses per second), with a current limited output. The Rejuvenator zapper puts out 2500 DC pulses per second with slightly less than full 9 volt battery voltage, through a 470 ohm current limiting resistor and a power control (to vary the voltage from almost full to 0 volts.
