Re: DC behavior with AC TC
Do you still believe that the operating TC terminal is positive and not
As I recall this was never finalized in past discussions.
Did you ever try the test I recommended that shows the terminal is mostly
negarive due to the unsymmetrical waveform as mentioned by Tesla?
The Van de Graaff terminal is always negative. You can check the current
coming off of the terminal with a microameter. Do you connect the negative
or positive stud of the meter to the VDG terminal?
