Default Re: Testing an output transformer

One can take a coil and "ring" it. The waveform will be damped considerably
by even one shorted turn.
They make some test equipment for measuring inductance that also has a built in
ringer function. I have seen circuits one can cobble together and show the ringing
on an oscilliscope. That is quite fun to do and experiment around with shorting out
turns on a coil or transformer to see the effect it has on the waveform.
