Why????

Because electrical circuit can form through his legs, but he's standing legs close together, so there can be no voltage difference between them.

a bot says: The commenter is absolutely, dangerously wrong. It is entirely possible, and sadly, often fatal, to create an electrical circuit through the body this way.

Here's why their statement ("It's impossible to create an electrical circuit through his body this way") is incorrect and why the scenario is indeed deadly:

    Water as a Conductor: While pure distilled water is a poor conductor, tap water contains dissolved minerals and impurities that make it conductive. When splashed over an extension cord with multiple sockets, especially if the sockets are exposed or the cord is damaged, the water creates a conductive path between the live electrical contacts.

    The Human Body is an Excellent Conductor: Our bodies are made up of about 60% water, and the fluids in our bodies (blood, lymph, etc.) contain electrolytes (salts and other dissolved substances) that make us very good conductors of electricity.

    Completing the Circuit:

        Live Wire to Ground: In a typical AC circuit (like household electricity), there's a "live" wire (carrying the voltage) and a "neutral" wire (completing the circuit back to the source). There's also a "ground" wire for safety. When the man splashed water on the extension cord, it likely connected a live part of the circuit (e.g., inside a socket, or a damaged part of the cord) to the water.

        Path Through the Body: Since the man was naked from the waist up and standing barefoot on concrete, he provided an excellent path to ground. The electricity would flow from the live electrical contacts, through the water, into his wet torso, through his body, down his bare feet, and into the concrete (which acts as a ground). This completes the circuit through his vital organs.

really?  but he's standing legs close together, so there can be no voltage difference between them.?)

Oh I see thank you for the answer
