No potential exists to evoke a current flow.
Hi Richard,
The potentials (energy) abound, you even describe them. The sum of
all voltages (energy) equal zero at balance (absolutely no power into
the load of the meter), but that does not mean there has been any
cancellation of energy - that is glaringly obvious. Remove the load,
and you can set the bridge adjustments ANYWHERE and there would still
be no interaction of energies.
At absolutely every segment of the circuit, there is a potential
difference, and all must exist to present the null (which is evidence
of a potential difference of zero, not evidence of no potentials).
This is Kirchoff's law in the raw.
Contrary wise, removing the source of energy will give an exactly
identical reading on the current meter, and to say that no energy is
the same as balanced energy is a shuffle on par with the old shell
game - King Lear muttering "Nothing begets nothing."
For cancellation of energy to exist, your analogy proves there must be
an identical energy present to offset it. This explicitly admits
energy remains in the face of narrowly inspecting an isolated instance
of balance (or cancellation - all the same, only a matter of
topology).
