My dad's co-worker asked me that, i guessed 50 feet because water does have some resistnace, but about 100,000,000 volts is still 100,000,000 volts but salt water conducts electricity better, due to the sodium. Please give your ideas they are greatly accepted!

It boils down to the voltage drop across your body as a function of distance from the point of contact...

Assume peak current of 30,000 amps and that the charge spreads out uniformly in all directions - as an expanding hemisphere.

Current density will be 30,000/(2*pi*r^2)....roughly 2400/radius^2 in meters. (amps/meter^2)

At 100 meters that implies a current density of about .24amps/m^2.

Assuming a conductance of 5mho/meter...that works out to a voltage drop of 1.2 volts per meter.

You're safe a football field away. At 30 feet though, you might as well hold a paperclip in each hand and stick them in a wall-outlet.

It would depend on the size of the lightning bolt, the overall depth of the water body, the conductivity of the electrolytes (salts) in the water, whether or not you were touching ground (branches, weeds, bottom) in the water, how far you were from the bottom, the turbidity of the water and total suspended solids in the water, and any number of other factors.

In all, I'd say it'd be a good idea to get out of the water before the lightning strikes.

Theory is fine, but I'm an experimentalist. Next time it is raining and there is lightning, get a group of friends together and align them all over the body of water. Hopefully, a lightning bolt will strike and someone on the shore (preferably yourself) should take note of its location. Then its simply a matter of identifying who actually survived and measuring the distance between the spot the lightning struck and their location(s) to aproximate the minimum distance. You may need to try this multiple times to get good error estimates. I hope you have a lot of friends.

i would say in fresh water 75 ft in salt water 100+

it would depent on the size and charge of the bolt caues the larger the bolt the larger the dicharge

If you are within arms length it would take a miracle to survive.

the SALT will turn to PEPPER stable question, would each thing interior the sea be electrocuted????? i think of it does no longer KILL the fish. they are risk-free by potential of the salt ion channel.
