Yeah, at a million volts alternating current.
The charger transforms the current to DC. It's like dropping a flashlight into the bathtub and getting killed.
No, that can be very safe. I built a Tesla coil that produces 2 million volts at high AC. . . and it just passes right over the skin. DC? It would likely kill immediately.
No, at 60Hz, 0.1 amp transthoacic charge for 3 seconds is adequate to induce ventricular or aortic fibrillation.
Skin resistance is overcome at about 30V and depending upon the path of the current, will effect the body differently.
500 ohms is standard resistance of the human body (sweaty or wet skin with good grounding).
Simplified Ohm’s Law of V=IR, 0.1 amp x 500 Ohms = 50V. Hence OSHA requirements for insulated conductors for anything above 50V.
The current doesn’t always gross the heart, so not everybody dies from 50V shocks.
The bodily perception of the shock has a threshold of about a milliamp and 5-10mA will be painful.
A Taser uses high voltage with little pulsed current, causing muscular fibrillation between 2 wires with darts penetrating the skin, inducing a current pathway between them.
