[TCML] Optimum ground conductor

[Carl Noggle]

Jim Lux is right.  The inductance of several feet of small wire is about 
1 or 2 microhenries.  The inductive reactance of this is an ohm or two.  
(X=2pi f L)  Even a large coil has a pulse current of less than an amp, 
so the voltage drop would be at most a few volts.  However, if you are 
jumping sparks from a grounded object to the top toroid, these sparks 
can have many amps of current which can create a big ground voltage at 
the end of a long ground wire.  I can attest to this from personal 
experience.
