it is rectified through a few diodes, and maybe regulated to a maximum voltage but we’ll get to that in a minute. Normally, DC voltage dividers are made with a pair of resistors. Combined ...

The diode is referenced to a voltage divider, and voila! Your LM7805 is now putting out a steady 9 V. How did [0033mer] become adept at doing more with less? As he explains in the video below ...
