Electricity And Water |

If someone throws an extension cord into the water right next to me, I
understand I'm probably going to be electrocuted. If they throw it in
the water a mile away, I'm probably not. What determines the
dangerous distance from the power cord? Is it a sphere with its
center at the cord's end and its radius the distance to the ground? Is
it different in salt water? Does the voltage, or the capacity of the
wire matter? Is DC (lightning) different?
