im trying to build an AC to DC powersupply using 1n4002 rectifier diode
the datasheet says
forward voltage 1V
but the book says that Si has 0.7V threshold
but when measured by the DMM(using the diode symbol in DMM) its 0.58V
which one should i use in my calculation.?
also what voltage does the DMM measure? Average? RMS? or Peak?
i measured my filter capacitor in my DC supply to be around 15V using my DMM in "auto DC". is that the peak? because my calculated average filtered voltage is 9.98V.
