When high voltage contacts the human body, the current forces its way through the skin and causes muscles to clamp in a tetanic contraction that can snap bones; simultaneously, internal resistance converts electrical energy into thousands of degrees of heat, causing blood vessels to vaporize and creating internal steam pressure that leads to explosive exit wounds, making immediate circuit breaking essential for survival.

What Happens If You Touch High Voltage?
Added:You don't just get shocked. [music] When high voltage hits, your body becomes a living heating element. In a fraction of a second, the current forces its way through your skin, searching for the fastest path to the ground. Your muscles don't just twitch, [music] they clamp.
This is called a tetanic contraction.
It's so violent it can snap your own bones. But while you're frozen in place, a much more silent and terrifying process is starting deep inside your tissue.
It's called internal cooking, and you're about to see why it's almost impossible to stop.
>> [music] >> Once the current is inside, your internal resistance turns that energy into thousands of degrees of heat. Blood vessels don't just burn, they vaporize.
[music] This creates internal steam pressure that has to go somewhere. Eventually, the current finds its way out. These [music] exit wounds are often explosive as the energy literally melts its way through.
To survive, you have to break the circuit immediately, >> [music] >> because once the current stops, the cooking continues from the inside out.
This is the science of the shock.
