Discussion Overview

The discussion revolves around the safety of using a multimeter to measure voltage while being part of the electrical circuit by grounding oneself through a conductor inserted into a ground outlet. Participants explore the implications of current and frequency on human safety, particularly concerning the heart.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant expresses a desire to measure voltage across their body and questions whether the current and frequency would be safe.
  • Another participant warns that household AC at 60Hz could potentially induce heart fibrillation due to its alignment with human heart rates.
  • Several participants strongly advise against the proposed method, emphasizing the dangers of creating a current path through the body.
  • Concerns are raised about the reliability of voltmeters for ensuring safety in this context.
  • A participant indicates they are reconsidering their approach based on feedback from others.
  • One participant references a chart illustrating the dangers of electrical current levels, highlighting the significant risks involved.

Areas of Agreement / Disagreement

Participants generally agree that the proposed method is dangerous and should not be attempted. There is a consensus on the risks associated with electrical safety, but no agreement on the safety of the original proposal.

Contextual Notes

Participants express concerns about the assumptions underlying the safety of using a voltmeter in this manner, particularly regarding the effects of current and frequency on the human body.

will i be safe if i...

i stuck a conductor inside ground outlet. I touch it so that i am grounded (i don't trust the carpet floor to properly ground me) next i want to take my multimeter and read the voltage across me and the hot outlet. since voltmeters have high resistances, i should be safe right?

basically i want to measure the voltage between ground and hot which I've done many times... just that, this time, i want me to be part of the circuit.

so.. two questions..

will amount of current going through me be a safe amount?
&..
will the frequency going through me be safe for my heart?
since.. I've been told that even if there's not a lot of current, the frequency of household electricity is quite well tuned to mess up the human heart.
 
Engineering news on Phys.org
yes household AC at 60Hz is a multiple of the human heart rate at 60 to 100 beats per minute so it could basically put your heart into fibrillation mode.

Why can't you just use the volt meter to measure and skip going through your body?

You want to be part of the circuit, please stay away from anything electrical that is the LAST thing you want to do regardless of voltage or current.
 
Ohhh dear,
another Darwin Award in the making !

Mentors, please lock the thread and give the OP a strong health and saftey warning

It can also be the last thing you actually do in your life.

Don't trust voltmeters for safety.
Don't do that.
 
just so i don't get my account locked or something like that for this silly reason, don't worry... I am not going to do it if everyone is telling me it's dangerous. that's why I am checking first with people
 
Thank goodness lol, first rule of working with anything electrical, regardless of how much voltage or current keep yourself isolated from the circuit. Never create a path for live current to flow from source through you to ground.

if you look at the chart I posted just now, then consider your post above at 15 amps on that 120 socket. which is 150 times stonger than the dangerous levels on that chart. You can easily see why we responded the way we did.
