I have a transformer that says 6V 600mA 3.6VA, AC current (but the voltage measured is actually 8.65Vac).
I will add a 4 diode rectifier WITHOUT capacitor (I say without in order to simplify the calculus). I want to connect LEDs (200mA per LED). So, I should be able to connect 3 LEDs.
I want to know how to calculate the series resistor for each LED. But I don't know the REAL output voltage of the transformer. Will the voltage drop after I add each LED (this is what I think it will happen) or only after I reach the maximum power consumption?
