DC wise its the same & works the same. You can check continuity
the same. If you know what freq it is designed for yes you could do it
that way. But the farther you go from that freq the more current it
draws & eventually it is seen as a short.......
Look at an amp. Output xfmr made to pass say 20h-20kh.
If you could get say 50kh through it the 6L6's wouldnt like
it & would glow cherry red & meltdown. Same idea. Go to
the secondary & it says "use 4-8-16 ohm spkrs". Use a 400 ohm spkr &
you barely hear it. Its not really ohms DC wise, but impedance. How things behave with AC & complex signals. Beyond that we get into engineering.
I wont go there, its better to look like a fool than prove it to all !!!
Oh yes, how the xfrm knows. its in the core material, windings,
spacing etc...........
