Quick explanition

I have a transformer.....it puts out 5.00VAC and on the same wire 3.46VDC how does this work?

your transformer has more parts inside than just windings = possibly some diodes and maybe a chip and a capacitor or two ...

Do you mean your multimeter reads '5.00' on an AC setting and '3.46' on a DC setting?

Some multi meters also have 'issues' with reading voltages properly.

the 5vac could be 'supply ripple'.
the 3.46vdc could be measurement error of the meter.

Load the plug pack with a small fillament bulb and then see what your meter says.

(small bulb, say something like a 6v torch bulb)

EDIT; if it is an actuall mains transformer with NO other components (diodes etc) then I garrentee your meters a cheap/nasty/faulty one)
