Occupational safety experts have developed an alternative criterion for electrical safety. They have found that shocks lasting less than 3 s will be nonlethal if the product of the voltage drop across the body, the current through the body, and the time ( ≤ 3.0 s) that the current flows does not exceed 13.5 V • A • s = 13.5 J . Suppose that one hand of a potential victim is grounded and the other hand touches a voltage source; suppose further that his skin resistance is negligible—a worstcase scenario. Using the criterion above, what is the lowest voltage that will not be lethal for a shock that lasts 1.0 s?
