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...........

Thanks Zeno and yes the EE part is mind-boggling tstl when you start getting into the formulars in the complex domain. Transformer lingo can get as hairy as you want to make it and I've seen and done a tad and it's not any fun but to an EE may be but I'm not one of those and don't want to be !!

I'll try to get to that site and see if those cats can help me out. TIA,
