Power supply output

  1. Aug 12, 2011 #1
    I am trying to make a capacitor by connecting + and - to the electrodes between two parallel plates. There are + and - and Ground in the power supply which of these should I connect to the two plates and how does it work.


    thanks

    I am having a problem to understand how this power supply works. (attached) photo.jpg


    could anyone please explain to me how it works. I am confused with the ground part. Also, I do not know what COM is?

    Ignore it.

    You simply do not need it.

    If you have a DMM check resistance from that terminal to the ground prong on the power plug. They may be connected.

    I would guess that the Com terminal is just that, common. Again use your DMM to check resistance between the 2 com terminals.
