Consider input voltage is 230Vac/ 50Hz I am applying through Full bridge rectifier what will be the DC voltage at output?
A smoothing cap does not (cannot) "add" voltage as you are suggesting.Here is a simple calculation but should we have to multiply 1.414 also if we don't have high value smoothing capacitor with bridge rectifier while calculating average DC output? Anyone please!
A smoothing cap does not (cannot) "add" voltage as you are suggesting.
Mulitplying the RMS voltage (as indicated by, say, a normal VOM) by 1.414 ia necessary to give us the peak voltage level available to the rectifying circuit and, ultimately, the maximum resulting DC value as per the formula of the example.
Since you quoted me in your post, I should point out that I was responding to Willen's post (#2) wherein he seemed to posit that a cap could "add" to the peak voltage, thereby increasing that peak value which, of course, it cannot.If there's no load, then smoothing cap charges to the peak voltage and stays that way. So, it does "add" voltage by keeping voltage steady between peaks...
