"That's a fallacy. It simply isn't."
Dave, it would be helpful if you'd supply your reasoning.
In many ways I regard ground as just another conductor. However, unlike
a wire, it is normally without resonance effects. That's the "current
sink" aspect. Current will flow from a wire into ground if you make a
connection. If you're using a ground rod, the impedance at the
connection depends on the rod length, rod diameter, and the
characteristics of the soil. If the soil is uniform, reflections don't
occur, unlike for a wire of finite length. The current dissipates as it
spreads within the ground, which acts like an infinitely long wire with
a traveling wave. However, when ground strata are distinct and well
defined, resonance can occur. An example shown for the stratified ground
calculator described in the writeup below exhibits strong resonance. A
water table 200 feet below a desert surface magnifies surface ground
conductivity by a factor of 10, which is pretty amazing. I think such
situations are rare because I suspect most variation in ground
characteristics occurs gradually rather than as distinct strata, which
is necessary for resonance.
