Both Thomas Edison and Topsy the elephant say that AC is more dangerous. Of course, those two might be slightly biased against AC. ;)

But seriously, both can be dangerous depending on the amount of current and which part(s) of the body the current runs through. Some sources indicate that AC current is more likely to cause muscles to contract, making it harder to let go of whatever is electrocuting you. However, I have no experience to know if this is indeed correct. Disclaimer: Don't try any experiments that involve electrocuting yourself and/or others. Jimmy Kariznov · 4 years ago

@Jimmy Kariznov That was great! Your last sentence reminded me of a blog post that deals with electricity (although that post has nothing to do with this question). Mursalin Habib · 4 years ago

From what I know, DC is more dangerous than AC. Consider both AC and DC are having same peak voltage of say, 230 volts. You know, that AC has positive and negative cycles and there are points where the voltage becomes zero, whereas DC is static - it is not varying. So suppose your house mains supply is DC instead of AC, and by chance you touched the live wire with bare hands. Now since it is DC, it will continuously burn you up and you will be dead in a matter of seconds. Note there are no zero crossings. So, when you touch a DC supply, you are stuck with it until you are dead or somebody throws you away from the contact. Whereas consider AC - here, there are zero points and since there are 50 cycles in one second, there will be 100 zero crossings in one second. So, if you touch an AC supply with bare hands, there is a chance for you to draw your hands back, before the supply burns you out. And also, the AC supply, since is not continuously static, will take more time to burn something as compared to DC with the same peak voltage. With said all this, I hope you get the basic idea.

@Ajay Maity Really voltage has nothing to do with it. Consider electricity to be a river you have voltage which would be how much water there is and then you have amperage which would be how the current. It doesn't mater how much water there is its the current that dangerous John Voga · 3 years ago
