Im a novice and trying to understand the logics here. My monitor has the
120v AC line coming into a Full bridge rectifier(4 Diode set) with 3 .01
filter caps. Why do I get 183volts DC out the other side and not 120volts
DC?
If a picture is required let me know



The output of the bridge rectifier should go through some filtering that has
large electrolytic capacitors. The unloaded voltage would be 1.414 * RMS or
1.414 * 120 = ~170 VDC. The fact that you are reading 183 VDC shows that
there is no load on the power supply! Something has open circuited, causing
a no load condition.
