Question

The resistance of the body varies from approximately 500 kΩ (when it is very dry) to about 0.900 kΩ (when it is wet). The maximum safe current is about 5.30 mA . At 10.0 mA or above, muscle contractions can occur that may be fatal. 1.) What is the largest potential difference that a person can safely touch if his body is wet? Express your answer in Volts using two significant figures. 2.) Is this result within the range of common household voltages? (Yes or No)

Step 1

900 k\Omega = 0.900 \times 10^3 \Omega\) Maximum safe current, \(I_{max} = 5.30 mA = 5.30 \times 10^{-3} A\) Show more…
