DC arcs do not "quench" as easily because voltage does not go through zero. Generally, if you don't puncture the skin, 30V has a good possibility of causing sensation, and 50 or 60V is almost certainly going to give you a shock that you can feel.
The voltage is generally considered to start being dangerous around 50 or 60V. In a wall socket V AC , current may travel through any path though your body to ground. For example if you touch the hot side with your right hand and your left foot has the best ground, current could travel across your heart and possibly kill you. One Volt is defined as energy consumption of one joule per electric charge of one coulomb.
Second, lightning is a direct current DC that would require it to be converted to alternating current AC so it could be used for lights and other equipment. With AC , the current travels on the skin of the conductor while with DC , the current flows throughout the entire conductor and not just the conductor skin.
Do amps or volts kill you? Category: science physics. So, back to which kills you , the amps or volts. Given your body is a constant resistance, it really is a combination of both. Higher voltage means higher amperage, and thus higher voltage has more potential to kill.
It takes only mA to stop your heart. How many amps is a Taser? How many amps is a 12 volt?
