What best describes dynamic stray currents?

Dynamic stray currents are characterized by their variability and responsiveness to a range of factors, particularly environmental changes. These currents do not remain constant; instead, they fluctuate based on a variety of conditions such as moisture levels, temperature changes, and alterations in the surrounding electrical environment. For instance, increased moisture can create better conductivity in the soil, which can lead to changes in the flow and intensity of the stray currents.

The nature of dynamic stray currents makes it essential for cathodic protection professionals to continuously monitor and adapt their strategies to manage these currents effectively. This adaptability is crucial because static interventions may not adequately address the variable nature of stray currents, hence the importance of recognizing and understanding their dynamic behavior in practice.
