how we feel the elecric shock? Its hazardness to the body depends on voltage or current?

Answer 1

It's always the amps that kill. The way I think of it is like a giant tank of water with a tap. The amount of water in the tank is the vltage, the amount of water that comes out the tap is the amperage. The amperage is a measurement of the actual current (flow of electrons). The voltage is a measure of the amount of electrons (the tank). It doesn't matter how much is in the tank, it's the amount flowing that kills you.

Answer 2

It is not the voltage but how it is applied . If u are in water it can be very dangerous. The Current is what kills . It is like this there is a window where it is most critical. The window is from 100ma to 200 ma . In that window it will cause the heart to fibrillate. If it is above 200 ma u will get burns and if that doesn't damage something important u will probably make it.

Answer 3

It depends of voltage which itself depends of the current absorbed by the body : ==>
An electric shock can occur upon contact of a human or animal body with any source of voltage high enough to cause sufficient current flow through the muscles or nerves. The minimum current a human can feel is thought to be about 1 milliampere (mA). The current may cause tissue damage or heart fibrillation if it is sufficiently high. A fatal electric shock is referred to as electrocution
It is sometimes suggested that human lethality is most common with alternating current at 100-250 volts, however death has occurred from supplies as low as 32 volts and supplies at over 250 volts frequently cause fatalities.

Electrical discharge from lightning tends to travel over the surface of the body causing burns and may cause respiratory arrest.

The voltage necessary for lethal electrocution depends on the current drawn by the body. Using Ohm's law, Voltage = Current x Resistance, we see that the current drawn depends on the resistance of the body. The resistance of our skin varies from person to person and fluctuates between different times of day. In general, dry skin isn't a very good conductor having a resistance of around 10,000 Ω, while skin dampened by tap water has a resistance of around 1,000 Ω.

The capability of a conducting material to carry a current depends on its cross section, which is why males typically have a higher lethal current than females (10 amperes vs 9 amperes) due to a larger amount of tissue. However, fatality can occur from currents as low as 0.1 to 0.3 amps.

Electric current (amperes) Voltage at 10,000 ohms Voltage at 1,000 ohms Maximum power (watts) Physiological effect
0.001 A 10 V 1 V 0.01 W Threshold of feeling an electric shock
0.005 A 50 V 5 V 0.25 W Maximum current which would be harmless
0.01-0.02 A 100-200 V 10-20 V 1-4 W Sustained muscular contraction. "Cannot let go" current.
0.050 A 500 V 50 V 25 W Ventricular interference, pain, respiratory difficulty
0.1-0.3 A 1000-3000 V 100-300 V 100-900 W Ventricular fibrillation. Can be fatal.
6 A 60,000 V 6,000 V 400,000 W Sustained ventricular contraction followed by normal heart rhythm.
These are the operation parameters for a Defibrillator. Temporary respiratory paralysis and possibly burns.

Answer 4

Current.

Answer 5

The current is more deadlier than the voltage.

Just a current of 0.1-0.3A can cause the heart to stop.

Answer 6

Generally speaking it is the current that will kill you, but voltage is also a factor

Answer 7

Its volts that jolts, by amps that kill!

Static shocks can be thousands of volts and doesn't do you much harm. Its current that can kill you.
