- Ah, but it would - unless the person built a power supply with built in
- capacitors and a voltage regulator. I suspect that such a contrivance
- would be rather hazardous.
-
- If the person simply rectified the current then - with a half-wave rectifier,
- the current would pulse at 60 hz (1/2 that of a 60 hz AC voltage, which
- pulses at 120 hz) or - with a full-wave rectifier, the current would pulse
- at 120 hz.
-
- It is questionable that anything in the human body resonates at either 60 Hz
- or 120 Hz either.
