If you use 2 diodes in the first circuit, will be still half way wave?

@lolopli1

If the diodes are in the same direction, there is no change. If the diodes are in the opposite direction, there is no electron flow.

But what happens to the negative charge? Is it lost as heat?

[AllAmericanFiveRadio]

@Dark0Lord7

A charge is both positive and negative.

i love this video, please keep it posted. Question, what would be an approximate needed value on the resistor and the caps if we're applying 120vac ?

Thanks gurtobe

For an AA5 radio the voltage for the electrolytic capacitor is 150WV, Working Voltages. The resistor is about 1K @ no more than 10 watts. The capacitance for the Pi filter range from 30MFD to 80MFD for each cap. Usually the higher MDF cap is first from the diode. I would Google Pi filter power supply.

Thanks a lot. Can you do one one how to understand the use of an Oscilloscope if you can please.

Nop, electrons flow from negative to positive.
