Voltage doesn't harm you. Current does. If you can sufficiently reduce the resistance
at the points where the power supply connects to your body, you can do yourself
a lot of harm with a very small voltage.
I am an electrical engineer. We were discussing this exact question in the engineering
dorm, on a night more than 50 years ago that I can never forget. A debate got going
over whether it's possible to kill someone with 12 volts. Some said yes, some said no.
A very stupid proof of concept was proposed, and played out to its unfortunate
conclusion. A method of low-resistance connection was proposed, and one of those
who said it couldn't be done bravely demanded to be the one to demonstrate it,
and show everyone else that it couldn't be done. The power source selected was
a 12-volt car battery, the means of connection are better left not described, and
for the rest of the night, each of us in the group was interviewed privately, one
at a time, by the police, after his body was removed from the dorm.
So I'll say: less than 12 volts, if you know how to do it.

Why high voltage does not kill?
Its not voltage that kills it is current.High voltage CAN kill, if it can also provide high current (especially if the current comes near the heart as it takes under 1mA to stop the heart which isn't much current).However if the high voltage source is current limited and/or the current only passes through the extremities it is very unlikely to kill.
What is more dangerous voltage or current?
Current is what is can hurt or kill you.
Where are Vpp and V rms?
Vpp is Peak-to-Peak voltage, in other words, in AC voltage, the peak-to-peak voltage is the potential difference between the lowest trough in the AC signal to the highest. Assuming the reference to the voltage is zero, Vpp would be twice the peak voltage (between zero and either the highest or lowest point in the AC waveform). Vrms is the Root Mean Square voltage, think of it as sort of an average (it's not quite that simple). For a sine wave, the RMS voltage can be calculated by y=a*sin(2ft) where f is the frequency of the signal, t is time, and a is the amplitude or peak value.
Why can a shock from mains electricity kill you?
it can stop your heart Certainly UK mains voltage,,240 V ac is enough to kill an average person
Why is it dangerous to climb electricity pylons?
Because you can touch the live wires and the voltage can kill you.CommentIt's quite unnecessary to 'touch' the live conductors. Approaching them within a few metres (depending on the voltage) will be sufficient for the high voltage to 'flash over', and inflict fatal burns. And if the burns don't kill you, the resulting fall will certainly finish you off!
How can you identify the Primary and secondary winding of a transformer through input and output connected wires without using multimeter?
Usualy the largest current is at the lowest voltage side ; so the largest conductor section determine the lowest voltage side ; if the transformer is a set up one , the primary will be the lowest voltage winding ; in the other hand , it 'll be the highest voltage winding
What is the lowest stimulus voltage that induces active force in the skeletal muscle?
It is called the threshold voltage and is around -70 mvolts.
A sentence with voltage in it?
Voltage can kill a person even if you are only meters away.
If you have several cells of say 9V in parallel the total voltage will still be 9V so what happens if all the cells are of different voltages?
You get the lowest voltage. Although it's not quite that simple. The higher voltage batteries will charge up the lower voltage ones to some extent, so you'll get the highest voltage that the lowest voltage battery can support while being charged by the other batteries.
How much voltage dose it take to kill an average person?
It's not the voltage that kills - it's the amperes. A few millivolts can kill if the amps are high enough.
What is the highest and lowest voltage of an electromagnet?
The strength of an electromagnetic is determined completely by the current through its coil, and doesn't depend on the voltage across the coil. The voltage will be (current) x (resistance of the coil).
Can over voltage kill a car battery?
Yes
Can the lowest acid on to pH scale kill you?
Definately

How much voltage is needed to kill a human?
The voltage needed to kill a human being is 10,000,000,000 volts. Ok im not the one who answerd this question i have a question of my on... you say its about 10,000,000,000 but how fast could that kill you and another question How fast could 2million volts kill you if it could kill you? please answer back
WHAT IS THE LOWEST VOLTAGE NEED TO LIGHT A LIGHT BULB?
A light bulb is manufactured to operate on a specific voltage. The voltage can be a low as needed and the manufacturer will compute the size of the filament that is needed for a specific wattage. If you are referring to a threshold voltage then that is another question that needs to be asked.
