Part 4/9:
To test this, a single rod would be driven into the soil first, and its electrical readings would be recorded. Subsequently, both rods would be connected together to determine if adding more metal surface area impacts the grounding effectiveness.
Methodology and Future Tests
The testing strategy involves measuring electrical resistance or conductivity around these rods. If connecting the two rods does not significantly improve readings, it would support the notion that depth outweighs surface area in grounding performance.
