Final answer:
Creating an earth wire can be an effective safety measure in some situations, as it provides a path of lower resistance for the electric current to flow through, away from the person.
Step-by-step explanation:
Our bodies are relatively good conductors due to the water in our bodies. When there is a direct path to ground, large currents will pass through the parts of the body with the lowest resistance and a direct path to ground. Wearing insulating shoes, a requirement in many professions, prohibits a pathway for electrons by providing a large resistance. Creating an earth wire can be an effective safety measure in some situations, as it provides a path of lower resistance for the electric current to flow through, away from the person.
