Which of the following explains the risk of electrical shock when touching a conductive path?

• A. Grounding potential
• B. Touch potential
• C. Safety net
• D. Electrical gradient

Answer: (B)

Touch potential refers to the voltage difference that exists between a grounded object and a conductive path, which a person may come into contact with. When an individual touches a conductive path that is energized, there is a risk of electrical shock because the body may complete an electrical circuit between the grounded object and the path. The higher the touch potential, the greater the risk of shock, as it indicates a significant voltage difference that can drive current through the body. Understanding touch potential is critical for personnel working near electrical installations and utility systems, as it highlights the dangers of interacting with conductive materials in close proximity to energized equipment. This knowledge is essential for identifying safe practices and mitigating risks associated with electrical exposure.
