e cap negaive to ground
Hi all,
Just a simple question on the use of e-caps.
We all know that e-caps block DC when fully charged and allow AC to pass (most) of the time. What I'd like to know is,
1) if I tap the output of the e-cap from the negative terminal, with reference to ground (with my digital multimeter set to Vdc), would I get a negative voltage readout?
2) I've always known to connect the positive terminal to positive terminal (or terminal with the higher potential), so why do some circuits reverse this connection? Does the e-cap perform some form of inversion of voltage?
Regards,
FK
