What is the primary natural protection against electrocution?

• A. Muscle reflexes
• B. Bone structure
• C. Skin resistance
• D. Hair density

Answer: (C)

The most important natural protection against electric shock is the skin’s resistance. Dry, intact skin acts as a barrier that limits how much current can enter the body, so the risk of harm stays lower when the skin is dry. When skin is wet or damaged, its resistance drops dramatically, allowing much more current to flow and increasing the chance of serious injury or electrocution. Other factors like muscle reflexes aren’t reliable safeguards on their own, and bone structure or hair density don’t provide meaningful protection against current. The real safety comes from keeping skin dry and intact, and always de-energizing circuits and using proper insulation to prevent contact.
