Nice! How was it?

I just went to the aquarium. That’s shock is 3x more powerful than a wall outlet.

It was fun actually. They have a place where the stingrays swim up to you and you’re allowed to pet them. I was surprised by how they actually want to get pet. They swim up to the side of the wall and come out of the water to get your attention. Like a little water dog.
Thanks for asking!

Rays are awesome. I always tell my student divers not to approach them, but to enjoy it if they decide to be buddies.

I love stingrays and nurse sharks! They’re like little aqua puppies.

Speaking of sea urchins, I learned a while ago they like to wear shells and such like little hats to protect them from the sun. It's adorable.
Also, an aquarium 3D printed some hats for their urchins. It's pretty great.

Yeah I went to an aquatic petting zoo like 25 years ago when I was a kid with my parents in Mexico, and how cute the nurse sharks and the rays were and how much they enjoyed being pet still sticks with me today.
And that was a hell of a lot of beers ago, pretty sure it’s a core memory at this point.

That’s awesome! One of my most vivid early memories is petting rays at the Monterey Bay aquarium on a field trip in elementary school

wet.

Thats sick. Hope you had a good time

This is not true. The voltage is 3 times higher, that’s part of why it’s so debilitating. If the power (amperage) was 3 times higher that man would not have gotten back up. Their amperage peaks at about 1 amp, which is enough to do some damage.
deranger@sh.itjust.works 10 months ago
There’s no given amperage coming out of the wall. It’s a product of V=IR. Given a constant resistance for the person’s body, three times the voltage does means three times the current.
Sanyanov@lemmy.world 10 months ago
An eel can only generate so much power, so essentially the voltage will drop so that the power will be lower.
600V at 0,01A will just turn to, say, 100V at 0,06A if the resistance between two points will be 1667 Ohm.
In that sense, amperage is super important. We should always consider capabilities of the power source, this is big part of electrical grid engineering.
Sanyanov@lemmy.world 10 months ago
1A amperage is a feature of saltwater eels, ones that produce electricity at much lower voltages, like 10-80V. This is a natural adaptation allowing them to maximize power output in a relatively highly conductive environment.
The freshwater eels, the ones producing 600-800V, are only able to output about 0,1A, because that’s just how power works.
1A at 600V would be a guaranteed instakill for a human.

lol, I took that as you going to the aquarium to grab an eel and let us know its strength instead of relaying a fact that you learned there.

I like that universe better so this is what happened
postmateDumbass@lemmy.world 10 months ago
So much for that extensively planned eel heist.
Sanyanov@lemmy.world 10 months ago
Not 3x more powerful, but rather having 3x higher voltage.
But still enough power to shock an adult human.
DanglingFury@lemmy.world 10 months ago
But how many amps?
Sanyanov@lemmy.world 10 months ago
That will heavily depend on the surroundings, your body, and contact points.
Also, freshwater and saltwater eels approach it differently, with freshwater ones (the ones delivering those 600 volts) able to give out amperage of around 0,01A.
This may not seem like much, but it is actually enough to stun and paralyze a human under certain circumstances, and this is exactly what we see here. If there’s nobody to break the contact, the current will keep flowing for several more seconds, and if you’re unlucky, your heart can stop, with all the consequences it entails.

Needs clarification - do you mean a flowery, lacey, girly American electricity outlet, or a meaty, throbbing, frighteningly-erect rest-of-the-world outlet?
Iron_Lynx@lemmy.world 10 months ago
Thank you for making me picture the American wall outlet as a femboy, and the German Schutzkontakt outlet as a Giga Chad.
Sanyanov@lemmy.world 10 months ago
Meaty, throbbing, frighteningly-erect rest-of-the-world outlet
Mr_Blott@lemmy.world 10 months ago
Thanks for elaborately clarifying
