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
