Can a person’s received electrical shock be measured afterward with a device that detects how much electricity they got?

No—after the shock, there is no residual voltage left behind on the person, so you cannot wave a device over them to measure how much electricity they received [#21679818] The amount can only be inferred indirectly from the circumstances, such as the shock source, entry and exit points, and the resistivity of the skin and tissue [#21679820] It is the current through the body that causes damage, not “electricity levels” remaining afterward [#21679820] The thread notes that fatal shocks often occur around the 100 mA range, while higher currents more often cause severe burns and tissue damage [#21679820] In a fatal case, the source and injuries may allow a rough estimate of the power involved, but not a direct measurement after the fact [#21679818][#21679820]

If a person receives a shock of electricity, is there a way to measure after the shock, how much electricity the person has received? Is there a device of some type that could be used, perhaps waved over the person to determine electricity levels?

Hi Erik-There is no residual voltage left behind after a person has received a shock, so the short answer is no.This got me started thinking, though, and much the same as the wind velocity of a tornado is estimated by the amount of destruction caused, I imagine it would be possible if a person was killed by an electric shock, it may be possible to estimate the amount of power (notice I didn't say voltage) the person received.-Rick

Hi Rick,Wouldn't there be some kind of residual charge? Like an effect similar to static electricity?
Fatal shocks can occur at about 100 mA

As Rick said, no.However, it can usually be inferred, since the source of the shock would normally be quite obvious. It is current that causes the damage, that is determined by voltage, entry and exit points, and skin/tissue resistivity for example.A fatal shock normally occurs at low current levels, typically in the 100mA range, high currents usually cause severe burns and tissue damage.See https://en.wikipedia.org/wiki/Electrical_injury

Erik,
> "Is there a device of some type that could be used, perhaps waved over the person to determine electricity levels?"You're thinking of the Star Trek Tricorder, more specifically the medical one. We're not quite there yet...

What about if person received AC current similar to the type of crowd control devices Rick mentioned in another post?>A higher powered device could be further away. This is the same
principle on which a >microwave oven operates. One or more of the

Erik.... it occurs to me that you might be able to use an RF field strength meter to indicate if anyone is firing RF or microwaves at you...something like this one here. no too expensive and quite sensitive enough to pick up any malevolent energy fired at you. There is a downloadable manual at the page which would tell you more.

Hi David,
That's great! Thank you very much for the post!! Can it detect for instance AC (Alternating Current) energy?

Post #9 21679825 29 May 2018 17:46

Erik no, the one I linked to only senses 1 MHz to 1 GHz - ie radio waves only.But you can detect lower frequency AC with just an amplifier and a coil, the coil will pick up AC energy and amplify it to headphones. Or you can use an AM radio, they are usually pretty sensitive to high energy that is above our hearing but lower than the instrument above will detects.Which brings me to another theory. The use of infrasonics (Audio frequencies below our hearing, that is in the range of about 0 - 20 Hz) is also supposed to induce nausea and disorientation. A good quality sound level meter might pick that up. This has nothing to do with electricity - is is just high energy sound waves that are out of our range of hearing. If a sound meter picks up something but you hear nothing that could be it.

David, that's great! Any suggestions or links to purchasing such an amplifier and coil?
Infrasonics is a great suggestion! What kind of distance could an infrasonic signal travel? And then what
would block infrasonic signals? Headphones? A hat that covered the
ears?

Topic summary

There is no residual electrical charge or voltage left in a person after receiving an electric shock, making direct measurement of the amount of electricity received impossible. The damage caused by the shock can sometimes be used to estimate the current involved, which is the primary factor in injury severity. Fatal shocks typically occur around 100mA, while higher currents cause burns and tissue damage. Devices like RF field strength meters can detect radio frequency or microwave energy but cannot measure low-frequency AC current directly. Low-frequency AC can be detected using an amplifier and coil or sensitive AM radios. Infrasonic audio frequencies (below 20 Hz) may cause physiological effects such as nausea and disorientation and can be measured with sound level meters, though these are unrelated to electrical measurement. Non-lethal crowd control devices emitting microwave or RF energy may cause temperature increases detectable by specialized sensors, but no handheld device exists to "wave over" a person to measure electrical exposure post-shock.
