How electricity flows through your body.

In summary, the conversation discusses the distribution and effects of electricity in the body. It is explained that electricity spreads out and looks for paths of least resistance, similar to how lightning branches out. The body is a good conductor of electricity due to its high percentage of saline solution. The conversation also touches on the idea that everything can be explained in terms of electric forces, including gravity, and mentions the role of the electroweak theory and renormalization. The topic of conducting electricity through the body is discussed, including the potential dangers of disrupting the heart's electrical signals. The conversation also mentions past quack medical devices that used electricity for supposed health benefits, and the potential risks of experimenting with electricity on oneself.

I was curious when electricity goes through your body does it spread out or stay in one line like lightning?

it spreads out, looking for the paths with lowest resistance.

Lightning also spreads out much of the time, like branches of a tree. Not necessarily a single bolt. In the body, there would be a lot of branches.

To the Sam
The body is a high percentage saline solution ( like a big bag of sea water from whence we came ) -- the electrical current is distributed over the whole it is not branched or look like lightning --- exactly how is determined by the area of contact
to the electrodes , and frequency .
In a spark i.e you touch a high voltage source the source is small -- but the whole body behaves as an antenna because it is connected to the surrounding space -- in this sense 'you' are grounded by virtue of what is called your 'radiation resistance '
Low frequencies of electricity will pervade the whole body ( i.e your wall socket ) but High frequencies cannot penetrate very far , they induce surface currents which reject the electric fields and keep the currents at the surface . ( see 'skin effect ' Not Human skin ).

The brain, heart and muscles are also powered by weak electric forces. The decay of sugar in the brain is one example. Basically everything can be explained in term of electric forces, including gravity.

The electroweak theory is partly based on a mathematical trick called renormalization (cancellation of infinities). There should be another secret behind it.

Incorrect.

Everything except the strong and gravitational interaction (if there is such).

Hurkyl is pretty wicked =)
I believe that the body is a decent conductor of electricity because I mean, there's so much fluid in our bodies that is made up of salts and ions, which allows electricity to be conducted through the body. And as Starship pointed out, the heart is powered by slight electrical forces and if that gets disturbed by the extra amount of electricity running through your body, you could die.

Current will take the path or paths of least resistance through the body. If the heart is on this path, the current can disrupt the signal to the heart. I believe that a current as low as 50ma through the heart can cause the heart to lose sync and be potentially fatal.

If the heart is not in the current path then the body can conduct many amps and survive with perhaps some burns. Some times the burns can be life threatening.

Inadvertently, I once shorted a high current 500VDC power supply to ground through my little finger. It hurt and I had a pretty good burn on my finger, but my life was never threatened.

a test of electricity

I have recently been a bit facinated with arcing 2 fingers to a parallel circuit on the electrodes of ac adapters etc. the interesting part is that it has different sensations on body. it sometimes effects just the hand, other times the arm and more. no I'm not a sicko, i just find it interesting.
and on a more sensitive note, anyone ever experienced a feeling of energy running through body during regular daily routine?

There used to be a lot of 'quack' medical devices in the first quarter of the 20th century (most using glass tubing) to supply the body with small amounts of electrical discharge (it was supposed to feel 'invigorating'--even Tesla used and made up his own). However, there were, also, no records kept of how many people died using these items.

Do you also 'like' clothes pins and alligator clips?

Oooohhh... now you're getting into my scene... :-p

"high current"? if that power supply was good for an amp, i would say that your life was at some risk. you don't have to be Ted Bundy to have current paths diverted through other parts of your body. venecular fillibration can be assured if your heart gets 250 mA.

BTW, about 4 decades ago, i was a ham radio operator. Heathkit HW-100. 700 volts with about 300 mA. trying to measure that through the cage nearly put me on my butt.
 

Related to How electricity flows through your body.

What is electricity?

Electricity is a form of energy that is created by the movement of electrons. It can be harnessed and used to power various devices and systems.

How does electricity flow through the body?

Electricity flows through the body through the nervous system, which is made up of specialized cells called neurons. These neurons use electrical signals to communicate with each other and control different functions of the body.

What happens when electricity flows through the body?

When electricity flows through the body, it can cause muscle contractions and sensations such as pain, tingling, or numbness. In some cases, it can also cause damage to tissues and organs.

Can electricity flow through any part of the body?

Yes, electricity can flow through any part of the body as long as there is a pathway for it to travel, such as nerves or tissues that conduct electricity.

What can affect the flow of electricity through the body?

The flow of electricity through the body can be affected by factors such as the body's resistance to electricity, the amount of voltage, and the duration of exposure. Certain medical conditions or injuries can also impact the flow of electricity through the body.
