That does't seem like much, but if you wait for 10 minutes = 600 seconds, you get 600*0.1= 60 seconds. these numbers are not exact, just an aprox, so around one full minute that the positive spends on one bar more than on the other for every 10 minutes. After one hour, one of the bars is completely black and the other is light grey, almost intact. so you see the importance of having a 50.000% duty cycle PMW to generate an even formation of oxides between the bars, this results on a much cleaner batch.

    Also, i'd like to ask whoever knows, higher frequencies seem to produce less oxides at the same rate of colloidal silver generation than lower freqs. any comments? the duty cycle's exactness is less important at lower frequencies, so if high freqs is required, duty cycle is CRITICAL, thanks for your time.

    have a good day everyone

    Hi Carlos,

    In the Teslaian wisdom Frequency and Pulse have entirely different paradigm.. the first one is of the transverse EM nature.. when dealing with frequency of Transverse nature, the duty cycle does not necessarily imply... the role of the duty cycle here is played by the Amplitude of the Signal wave. not so with the Pulse wave.. duty cycle is essential here and determines the true Longitudinal nature of the Electromagnetism. the signal wave generated by way of Inductive spike or Capative dump needs to be duty cycled..try this out and it shall open up new doors of understanding on to your electroplating process here...
