(red-ct-red)? For full wave rectifier, do we enter the measured full (red-red) Secondary winding's DC resistance into the Secondary winding resistance field of the Calculator?? Or, do we enter only half (red-ct) of the full winding's DC resistance value? ?
If the later, should we take the measured red-red ohm value and divide by 2 since the two red-CT values are never identical?
(The off-load voltage of the two halves of the winding are never identical as well so I assume we use the full red-red voltage value divided by two.)

Thank you! and thank you for PSUD2!!!

Hi, you just measure one half.

As you say, they are likely to be different; I would recommend measuring across both (red to red) and dividing by 2 for our purposes (both volts off-load and ohms).

PSUD3 will allow a different off-load voltage and resistance for each half of the secondary.

ps: Don't forget the primary resistance as this forms part of the source impedance.
