[AMRadio] critical inductance or load current as you please

A little simulation here, showing what happens to a power 
supply's output from near zero to a bit of overload, to focus on 
the area where the "bleeder" or load current becomes high enough 
to meet with the 'critical inductance' value of the choke at 
hand. It makes a good case for a stout bleed. I hope it is 
interesting.

A simulated power supply made from a 3500V transformer with 240 
ohm impedance, a mercury vapor bridge rectifier, 15H choke, 40uF 
capacitor. Different loads were applied and the voltage/current 
data taken. A set of charts were made in excel to illustrate the 
behavior.
