My understanding is that it's not anything to do with the resonance of a heartbeat or anything like that. The higher frequency ac will experience much more of a skin effect and not penetrate into the body as much or as easily. That means there will be less current that will pass through the organs and heart, but more through your skin and outer muscles. That'll mean it'll hurt more but be more likely to be survivable since you'll have more time to remove the person from the power source.
- jaclaz 7y agoMost probably that is another part of the story, however it seems like there is the need of more current at higher frequencies: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19730001338.pdf https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/197300... Look around page 40. I was reporting what I was told at the time, anyway here is a chapter of an electricity textbook confirming (for what is worth) the added danger of low (50-60 Hz) frequency AC current: https://www.allaboutcircuits.com/textbook/direct-current/chpt-3/physiological-effects-electricity/ https://www.allaboutcircuits.com/textbook/direct-current/chp...
- simcop2387 7y agoInteresting, I wonder if the higher frequency ends up needing more current because the body can't respond as fast, acting like a filter because the muscles can only move so fast. Biology and electricity mix in interesting ways.
