Okay, cool. The word "net" just threw me off for a second.

Oh, so it's 893 amps, right? I don't know how I came up with that other number. "steel is a plenty good conductor for your nets, way better than seawater" I think we might not be on the same page. I still want to electrify the water, and I don't want the monster to have to...

So if I use all 11,000 volts. I would have around 2600 Amps. I'm thinking I'll have two heavily insulated cables with copper net at the ends, to stretch out and increase the surface area. I kind of don't want to do steel net because apparently it's a bad conductor of electricity. I...

Thanks for the math lesson! Very helpful.

This is probably a dumb question. But I don't understand how you got those numbers. It looks like you wrote Volts times Amps times the square root of three.And yet in your math, you divided those numbers. This confused me, but I suck at math, so if you could explain that, it would be awesome...

I think I'll go the more crude route, as you suggested, and have the cables connected to one of the diesel/electric engines. But I would still like to have some semblance of an idea of how many volts or amps would come out of this. Again, this is a 17 MW engine. I know you can't figure out...

The ship has four 17 MW diesel engines and two gas turbine engines. Lately I've been thinking I would have submerged electrodes across the hull, with pulse generators pushing out the current, as is described here...

I'm trying to figure out the equation to produce 300 volts in sea water. I learned that the resistivity of sea water is .2. So I think that means to produce 300 volts it would take a current of 1500 amps. Is that right? Thanks!

I want to thank you all for taking my question seriously. It has been a huge help. Metiman, you make some good points. Your list of physics rules was very helpful. "I think your biggest problem may be that seawater is a better conductor than any animal." But still, this defense works for...

"That would electrify the water, but only in the vicinity of the electrodes. If you used the whole hull as one electrode, it would create a field around a large part of the hull--that region near to the trailing electrode. Optimal would be something like 2 or 3 exposed electrodes running the...

Thanks for your reply! I'm not sure about using the hull as one electrode, though. Can you explain why you suggested that? If he attached two electrodes to the turbine, via really long wires, and then dipped them both in the water, using an electrode holder, do you think that would work?

Hi everyone, I'm writing a novel in which a character "electrifies" water. He sends electric currents through the water to fend off a monster. So obviously the current must be high in volts and amps. My question is, what would be the easiest way to do this? So far, the best thing I can come...

I knew that was how it worked with light but I didn't realize it is the same way with electricity and magnetism. So none of them need a medium, they all travel through empty space. Which make sense since they are all part of the same field anyways. Thx!

I understand that the electromagnetic field and light are tied together, and they all travel through big groups of photons and they all travel at the speed of light. And I get that light travels through empty space. But I am wondering what does electricity and magnetism travel through...

yeah that makes sense! It was just hard for me to make that connection between your clock slowing down and the light escaping. But really it is good someone mentioned the light escaping explains why time slows down if you move close to the speed of light, not the other way around. I...
