What happens to body resistance if the skin becomes wet, burnt, or blistered?

• A. Increases
• B. Decreases
• C. Stays the same
• D. Varies based on environment

Answer: (B)

When the skin becomes wet, burnt, or blistered, the body resistance decreases. This is because wet skin has a lower resistance than dry skin due to the presence of water, which is a good conductor of electricity. When the skin is burnt or blistered, it can disrupt the outer barrier of the skin, allowing more electrical current to pass through. As a result, compromised skin conditions significantly reduce the resistance of the body, increasing the risk of electrical shock and injury. Understanding this concept is critical for electrical safety practices, as maintaining higher body resistance can help reduce the likelihood of severe consequences during electrical exposure.
