| Feb 25, 2020 at 14:04 | comment | added | Neil_UK | Are you happy to put the current sensing element between load and ground, or must it be at the high 20kV voltage? What does 'about' mean, in the phrase measure a low current output of about 1nA to 10mA. Given the large dynamic range, will +/- 10% accuracy do? | |
| Feb 25, 2020 at 8:40 | comment | added | John Bart | Thanks for your answer Niel. I'm trying to design a Circuit to measure the current in a high-voltage (1-20kV) ,low current (1nA-10mA) DC system. I think I need to use a couple of high voltage resistors and op-amp??? I am not sure about this. Quite confused. Any idea? | |

| Feb 25, 2020 at 7:01 | comment | added | Neil_UK | Are you doing highside or lowside sensing? Draw a diagram showing how you intend to connect your source, load and sensing parts. Phidget appears to be a tradename for modules. The only hit I get for phidget's bridge is an interface to Wheatstone Bridge type sensors such as load cells. | |
