# The effect of high frequency AC current in a fresh corpse [closed]

1. Given two AC currents of the same intensity, eg 20 mA, but different frequency, 60 Hz and 20MHz, which one would be more likely to reach the heart ?

2. I've read about the skin effect and how current tends to flow on the surface of a conductor. Does that apply to a dead human body at this particular context?

3. Would the low frequency penetrate the dead body and reach the heart and the high frequency be confined to the skin?

• Low frequency AC is more likely to cause heart fibrillation than high frequency AC. I suggest you do some reading on the hazards of electricity on the body. Feb 16, 2014 at 8:20

To summarise the article, $20\text{ mA}$ for $60\text{ Hz}$ causes "severe pain, difficulty breathing, loss of voluntary muscle control", whereas $20\text{ mA}$ for $10\text{ kHz}$ is in between "threshold of perception, and painful", but voluntary muscle control is maintained.
