| jjcote: | Only one kind, but from what I heard on the radio, there were 13000 of them. So maybe they really meant "what kind of voltage". And the answer may have been "high". |

| levitin: | It isn't the voltage that kills you; it's the amps (current). The danger of drawing a current of 0.2 amps is much lower if there are only household voltages below the street. When the voltages are much higher, as in this case, the possibilities for drawing deadly currents is higher. See http://www.physics.ohio-state.edu/~p616/safety/fat... The human body resistance varies with a lot of factors (including hydration, which is why those body-fat scales can give such variable readings), [I use V = I * R in my daily work, although we're generally talking about microohms, millivolts, and milliamps.] |
