The minimum amount of volts to kill a human is unknown.

The current is the cause of death for humans.Humans have died at low voltages.Time is a factor.A current of less than 0.1 ampere can be fatal.The current depends on body resistance.When measured from finger to toe, the internal resistance between the ears is only 100 ohms.

Electric shocks are often depicted in physical comedies, and the plot proceeds as usual: the comic character accidentally gets to a wire without knowing the high current that flows through it.He receives a fatal shock that leads to a stereotypical shimmy, a charred face and hair that ends up like an umbrella turned inwards by the wind.

The question of why this fatal accident is perceived as funny is disturbing.There is a plausible answer here.At the moment, this discourse is irrelevant.We are not at all sensitive to electricity and how much of it will kill us.

It's essential knowledge for safety purposes.A human skull hovering over two crossed bones is the common symbol of danger on electrical circuit boards and generators.

The symbol is accompanied by the rating of the machine, which shows the high voltage under which it operates, and lets you know if you come in contact with it.The psychological trend has been set by the use of voltage.

We think that 10,000 volts would be more lethal than 100.This is only partially true.

Sometimes electric shocks can occur at household voltages of up to 42 volts.

It is not the caliber that kills us, but the bullet that shoots that.The true cause of death is the current that is pushed through the body.

Without a potential difference, there would be no current at all.Unless you touch the ground, hanging on a wire won't kill you.Hanging from the wire forms an equipotential with it, whereas touching the ground immediately creates a potential difference, which draws a huge current through the victim.

A current of 10 mA or less would not be fatal.The muscles start to contract as we approach 100 mA or 0.1 A.Due to the low resistance of the heart, a current of only 10 mA is enough to kill us.

The resistance of our skin makes it impossible for the current to reach the heart.The current would be fatal if it reached the heart.

We can't release the wire when the current is greater than 1A.This is a consequence of paralysis.

Unless immediate help is called, the heart can experience ventricular fibrillation, an uncoordinated, intermittent twitching of the ventricles, which causes ineffective heartbeats that can lead to death.

A further increase in the current leads to burns and unconsciousness.The contraction of the muscles caused by the shock is strong enough to cause the heart to stop.Exposure to such a high amount of current can cause terrible internal burns and lead to cardiac arrest.Death is possible.

The mechanism that protects the heart is designed to be very lucrative.With immediate medical assistance to the victim, the chances of survival are slim.Doctors use defibrillators to save victims of shock.
