Hello, I'm having a little problem. I made a Full Bridge Rectifier with an RS 605 and capacitor(and the other version with 4 diodes). i am getting a DC and AC ouput at the same time.But if i change the polarity in my multimeter probes im not getting AC ouput. What is going on? I tried connecting a capacitor and the DC voltage increased as well the AC output.(I'm using a transformer that converts 220v AC to 12v AC)(without capacitor DC voltage is 12v and 25v AC, and with the capacitor, DC voltage is 18v and AC voltage 40V). Please reply. Good Night.
