The signal from the transmitter always seeks which path?

Explanation:
The signal will follow the path of least resistance because electric current naturally takes the easiest route to flow. In buried utility locating, the transmitter injects energy into conductors and the surrounding environment, and the path with the lowest impedance—typically a metal pipe or cable or a highly conductive ground path—offers the least opposition to that flow. Energy concentrates along that easiest route, making it the strongest and easiest to detect. Paths with higher resistance impede the signal, and there’s no inherent tendency for the signal to move upward or in a random direction.
