<P> The International Electrotechnical Commission gives the following values for the total body impedance of a hand to hand circuit for dry skin, large contact areas, 50 Hz AC currents (the columns contain the distribution of the impedance in the population percentile; for example at 100 V 50% of the population had an impedance of 1875Ω or less): </P> <Table> <Tr> <Th> Voltage </Th> <Th> 5% </Th> <Th> 50% </Th> <Th> 95% </Th> </Tr> <Tr> <Td> 25 V </Td> <Td> 1,750 Ω </Td> <Td> 3,250 Ω </Td> <Td> 6,100 Ω </Td> </Tr> <Tr> <Td> 100 V </Td> <Td> 1,200 Ω </Td> <Td> 1,875 Ω </Td> <Td> 3,200 Ω </Td> </Tr> <Tr> <Td> 220 V </Td> <Td> 1,000 Ω </Td> <Td> 1,350 Ω </Td> <Td> 2,125 Ω </Td> </Tr> <Tr> <Td> 1000 V </Td> <Td> 700 Ω </Td> <Td> 1,050 Ω </Td> <Td> 1,500 Ω </Td> </Tr> </Table> <Tr> <Th> Voltage </Th> <Th> 5% </Th> <Th> 50% </Th> <Th> 95% </Th> </Tr> <Tr> <Td> 25 V </Td> <Td> 1,750 Ω </Td> <Td> 3,250 Ω </Td> <Td> 6,100 Ω </Td> </Tr>
