The resistance of the body varies from approximately 500 kΩ (when it is very dry) to about 1.00kΩ (when it is wet). The maximum safe current is about 5.00 mA. At 10.0mA or above, muscle contractions can occur that may be fatal.
a) What is the largest potential difference that a person can safely touch if his body is wet?
b) Is this result within the range of common household voltages?
