Difference between Vdc and Vrms | Electronics Forum (Circuits, …
320VAC peak to peak = 230VAC RMS -> Rectifier ->230 impulse DC with the losses -> capacitor -> almost fully flat line DC. There is no VDC RMS. Thats a bit different. VAC peak to peak /square root of 2 = VAC RMS We divide by the square root of 2 to get VAC RMS so we can use the same formulas as we use for DC.
Why does a multimeter show VAC on VDC power supply output?
They all should give just direct current and show some values in VDC mode, but the multimeter also shows nonzero values when positioned in VAC mode. But not on all power supplies. Why is this? For example a 12 V PSU shows 12 VDC, but it also shows 25 VAC, but other 12 V PSU shows just 0.00 on VAC with just slowly alternating +/- sign.

Where: V MAX is the maximum peak value in one half of the secondary winding and V RMS is the rms value as: V RMS = 0.7071 V MAX.The DC current is given as: I DC = V DC /R. The peak voltage of the output waveform is the same as before for the half-wave rectifier provided each half of the transformer windings have the same rms voltage value.
Can I use a higher voltage rating when replacing capacitors?
Replacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically larger, everything else being equal. Make sure they actually fit in the same space. Sometimes it is also safe to use capacitors with a larger capacitance (Farads).
