Guest,

You need to provide some context for the question. In most circumstances, neither one is dangerous.

Re: about AC n DC

Hello "Guest"

Please refer: http://electrical-riddles.com/topic.php?lang=en&cat=5&topic=136

Are you:" Author : Hamid - From: IRAN"?

Or do you just want the free answer from here, so you can place it there as your own work, then appear to be so clever?

Further:

DC voltages as small as 0.2 Volts at 0.003mA (milliAmps) have killed people.

Contrariwise, others have been struck by lightning, with some 20,000,000+ Volts DC of strike surge, and survived.

Likewise there are huge variations with AC power.

So my present answer is: It all depends on the various factors, and until you supply specifics, the Question is not possible to answer properly.

Reply here, with , and reform your Question.

Kind Regards....

.

Hello cnpower

What I said above is correct, refer: http://cr4.globalspec.com/comment/268700/Re-about-AC-n-DC

In certain situations even very small Voltages and Currents can kill - I have quoted certain figures which are factual.

Likewise in other certain situations, extremely high voltages and currents may not kill - I have quoted certain figures which are factual.

Your Question: <"....15v AC at 400cycles/sec or 15v DC

in both which one is more dangerous....">

is impossible to answer correctly, because I could show you situations where either would be deadly, and other situations where you would not feel a thing.

As I said earlier, the Question must be more specific, because there are so many variables.

Re: <"....you must tired at replying my thread. and you seem puzzle.....">

I don't intend to say anymore in that Topic Thread, because I have endeavoured to help you, with Copy/Pasted information you say you cannot see, but others can see easily, and have stated so.

Thus there is a single conclusion to be made:

The China Portal to the Internet, has settings which prevent your access to certain materials and Webpages, because it would show up that Government in bad light, there is no other conclusion to be reached.

I am not puzzled at all.

Kind Regards....

Yes you can touch them and be okay... but what if you shorted them out and one was a 1000Amp supply and the other only 1 amp..?

The 1000 Amp supply would cause arcing and severe burns etc...

"Its the volts that jolts and the mill(iamp)s that kills".

Context is so important. For example, an air pressure of 5psig is dangerous if it is propelling a manhole cover towards a person....
