220 volts is more dangerous than 110 volts because 220 volts can deliver more current although the severity of the electric shock also depends on the current, the path the current takes through the body and your individual factors.
220 volts can deliver much more current than 110 volts as 220 volts can deliver 22 milliamps and 110 volts can deliver 11 milliamps and 22 milliamps is more dangerous as it's more current.
220 volts is pretty painful but if you are able to let go pretty quickly which you should be able to then the pain should go away pretty quickly.
I found the pain of the 220 volt shock I got was pretty painful for a couple of minutes and in the instance of being shocked but I was able to let go quick and the pain went away pretty quick afterwards.
The pain from a 220 volt shock can cause muscle contractions, burns and even cardiac arrest in severe cases.
When the electric current passes through the body it causes involuntary muscle contractions that can be very painful.
220 volts will grab you in some cases and especially if you have slow reflexes.
In most cases coming into contact with 220 volts you should be able to let go pretty quickly like you would with 110 to 120 volts.
I've accidentally came into contact and touched 220 volts and even 240 volts on an dryer outlet that was supposed to be off but got turned back on.
I was able to let go quickly but some people have not been able to let go so it can depend on the person.
It's also the current that kills and not the voltage itself.
220 volts will kill you if you are shocked with it for long enough and if enough current from the 220 volts flows through the body.
Even though the voltage alone does not directly cause death, it's actually the current that is lethal and 220 volts is a high enough voltage that it can deliver a fatal enough amount of current in the right conditions and especially if the current passes through your heart.
If you grab 220 volts and can release from it then you will likely be okay but if you fall into 220 volts or cannot let go of it then it can kill you.
When it comes to the deadliest voltage there really is no single deadliest voltage that can kill you.
In reality it's actually the current "amperes" or amperage that flows through the body that kills and not the voltage itself.
The amperes or amperage determines how severe the shock from the electricity is and the potential for death.
The voltage is the potential difference and you can think of the voltage as being the push or pressure which drives the electricity through a circuit.
The current is the flow of the electricity.
The current is the actual flow of electrical charge that is measured in amperes.
Current is what matters when it comes to the electric shock being deadly as higher current that flows through the body can disrupt vital functions of the body which include heart rhythm and can cause severe burns.
While any current flowing through the body can become lethal it's mainly currents between 100 milliamperes and 200 milliamperes and above to be considered lethal.
Having a higher voltage source can also drive a higher current through your body although the current itself is the primary factor when it comes to the severity of the electric shock.
Even ordinary household voltage of 110 volts to 240 volts can be deadly if the current flowing through the body is high enough.
And even low voltages as low as 42 volts have caused death.
I've touched 240 volts and 110 volts by accident and I was able to let go quickly but some people may not be able to let go of the 240 volts so it can vary.
When working on electricity be sure the power is off to avoid any electric shock and lock the breaker box out to prevent the power being turned back on.
The route that the current also takes through your body also significantly impacts the severity of the shock.
