What is touch potential?

What is touch potential?

• A. Occurs when an energized object is touched and the current flows through the responder to a lower voltage ground.
• B. A measure of the resistance encountered by current in soil.
• C. A potential difference between two conductive surfaces at the same voltage.
• D. A safety procedure for stepping over a live wire.

Answer: (A)

Touch potential is the voltage difference that can push current through a person when they touch an energized object and provide a path to ground. When you touch a live conductor and your body creates a path to ground at a lower potential, current flows through you to that ground, which can be dangerous. This lines up with the idea that an energized object is touched and current travels through the person to a lower voltage ground. The other options describe soil resistance, a difference between surfaces at the same voltage, or a safety procedure, none of which capture the situation of a person becoming part of a live circuit through contact.
