Hello. Warning, it is probably a silly question and my english is not the best...
I have read about that but I can´t understand it. In one text about conecting a high voltage device, it says
- Positive polarity, with the cathode earthed and the anode at high positive potential
- Negative polarity, with the anode earthed and the cathode at high negative potential
I supose you get the different potentials with a symmetrical power supply but I never understand that. If you have -10 0 +10, you can have 10 or 20 volts depending the terminals, but I don´t see the difference if you have a 20volts supply whit a 10 volts connection.
And in the example of the text, in both cases there is the same potential difference being the anode at a bigger potential difference. I mean, what is the difference connecting the anothe at +1.000V and the cathode earthed or the anode earthed and the cathode at -100V??
Thank you
Best regards
