A person notices a mild shock if the current along a path through the thumb and index
finger exceeds 81 µA.
A. Find the maximum allowable potential difference without shock across the thumb and index finger for a dry-skin resistance of 5.4 × 105 Ω. Answer in units of V.
B. Find the maximum allowable potential difference without shock across the thumb and index finger for a wet-skin resistance of 2100 Ω. Answer in units of V.
