How To Discharge Positive Volts Build Up On Object Without Method Of Ground Wire And Resistor?

[russwr]

Comments needed on how to discharge low voltage positive charge on object (not static high volts) , by means of negative output miniature power supply of 5 volts passing through cathode of diode? Does opposite side of conductive object require a completed circuit such as a capacitor and wire? The flow of negative DC electrons of 5 volts neutralizes the positive charge and is continuously applied to object to keep it negative. A capacitor does not pass DC current through it, whether plus or minus and can have a circuit connection "electrically". Capacitor can absorb voltage. (Not regular electrical grounding desired through resistor)
Either the capacitor has to absorb energy or the input power has to be reduced in energy for the object neutralization process and continuously providing negative electrons thereafter.
There are 3 types of electricity - AC alternating, DC in one direction either positive or negative, and then pulsing DC with duty cycle on and off, either positive or negative flow.
The other problem is an oscillator circuit that says in the output data -- "square wave". There are 3 types of square waves as seen on oscilloscope. Positive above zero base line, negative square wave below base line and AC peak to peak square wave above and below base zero line!
2 batteries in series have 3 terminals, as negative volts with respect to ground in center, and proper placement of diode.
