Wiring up a filter copasitor?
For my Cold Fusion Project I was told to use a filter copacitor with the isolating transformer and the bridge rectifier. I have had some trouble understanding this. The mains AC runs through the isolating transformer and right after that I need to hook up the filter copacitior. How do I know which is positive and negative. I know AC alternates between + and - but when I need to hook it up to the rectifier I need to find + and -. How do I do that?
