hook a 1 uf unpolarized cap in series and apply a signal from an oscillator.
if it is a 600 ohm winding, it will resonate at about 70 hertz,
if 10 K winding , 20 hertz.
look for a bump in your sig gen, or measure the ac volts as you sweep the circuit.
when the ac volts are equally divided between the cap and the transformer, you have resonance, so at that freq, the reactance of the cap and inductor will be the same.
don't use a 10 k resistor, the math is all screwed up due to the j operator.
and excuse me, while i operate on this j.
