• Current in the body. The resistance of the body varies from approximately 500 k2 (when it is very dry) to about 1 kN (when it is wet). The maximum safe current is about 5.0 mA. At 10 mA or above, muscle contractions can occur that may be fatal. What is the largest potential difference that a person can safely touch if his body is wet? Is this result within the range of common household voltages?
