A normal dry body's resistance from thumb to thumb is about 2.6 meg ohms.
This is the body's outside resistance from point to point and not the body's internal resistance. One the shock has started the skin becomes burned and this starts to lower the outside body resistance to a lower value. The longer the burning continues the lower the outside resistance becomes until it reaches an inside body resistance.
The body's internal resistance is in the neighbourhood of 1000 ohms.
Using the same formula with the internal resistance and see the drastic current increase that will kill you.
The formula for amperage is Amps = Voltage / Resistance.
Using a voltage of 220 the formula is, Amps = 220/2600000 = .0000846 amps or .0846 milliamps.
Using a voltage of 220, the formula is , Amps = 220/1000 = .22 amps or 220 milliamps
Using a voltage of 480 the formula is, Amps = 480/2600000 = .0001846 amps or .1846 milliamps.
Using a voltage of 480, the formula is , Amps = 480/1000 = .48 amps or 480 milliamps
As you can see, as the voltage become higher so does the current that can flow through your body if you short across an electric potential.
The following list is the tolerances that the body can stand.
Less than 1/2 milliamp no sensation
1/2 to 2 milliamps Threshold of perception
2 to 10 milliamps muscular contraction
5 to 25 milliamps painful shock (may not be able to let go)
Over 25 milliamps Could be violent muscular contraction
50 to 100 milliamps Ventricular fibrillation
over 100 paralysis of breathing.

What determines the damage caused to the human body by an electric shock?
You experience an electric shock when an electric current enters your body. A current can enter your body when you accidentally become part of an electric circuit. Whether you recieve a deadly shock depends on the amount of current that flows into your body. Answered on: October 24, 2011.
What factors determine the severity of electric shock on the human body?
The conductability situation of the object of study determins the severity of electric shock on the human body.
What causes Electric shock injuries?
Electric shock injuries are caused by lightning or electric current from a mechanical source passing through the body
A woman experiences an electric shock The electrons making the shock come from where?
The electrons from the electric shock come from the flow of electrons through a conductive material, such as a wire or electrical appliance. When the woman comes into contact with the electric source, this flow of electrons passes through her body, causing the electric shock.
What determines how severe an electric shock will be?
The severity of an electric shock is determined by the amount of current that passes through the body, the path the current takes, and the duration of the shock. Factors such as voltage, resistance of the body, and individual health can also influence how severe the shock will be.
What do people often do when they get electric shock?
When people get electric shocks their body often convulses.
What is the difference from static shock and electric shock?
Static shock is a sudden discharge of static electricity, often felt as a mild tingling or stinging sensation when touching an object. Electric shock, on the other hand, is the flow of electric current through a person's body, which can result in injury or even death depending on the intensity and duration of the shock. Static shock is generally harmless, while electric shock can be dangerous.
Why electric shocks occur?
An electric shock can be useful to the body in these two situations:A Defribrilator - Used to restart a patient's heart if it stops beating.A Pacemaker - Used to send electrical impulses to the heart at certain timings to make it beat properly.
How do you get electric shock?
Electricity tends to travel towards the ground. when we touch an electrical substance, our body acts as a conductor and the current passes through our body to the ground. this is how we get an electric shock.
Why do you get an electric shock when you touch a door knob after walking on carpet?
When you walk on carpet, your body builds up a static electric charge. When you touch a metal door knob, the excess electrons are transferred from your body to the knob, causing a sudden discharge in the form of an electric shock. This is due to the difference in electric potential between your body and the door knob.
Identify what determines the damage caused to the human body by an electric shock?
The amount of current flowing through the body, the duration of the shock, and the path the current takes through the body are the main determinants of the damage caused by an electric shock. Additionally, factors like the electrical resistance of the body and the voltage of the electrical source can also affect the severity of the injury.
What are electric eels adaptations?
The electric eel's adaptations is #1, the electric shock.
