Why is there an AC component present in the DC portion of a full wave rectified signal?
Whats the best way to measure AC "ripple" and why?
I have 4 DMM's. If I measure the AC ripple (leads across the output), 3 of the meters read around 6VAC and one reads around 25VAC. Why would the one read 25VAC?
