Question

Why is ac more dangerous than touching a dc wire or ac wire?

Answer 1

No, it's not! Depends on lots of factors. People have given good answers. But here's a fun fact. A US Navy guy died out of a 9V DC battery. The spark which you see off metal door knobs and sweaters in winter are a minimum of 10,000 V. I didn't die of it. It's the current that matters –

Answer 2

After going through several forums, I became more confused whether it is DC or AC that is more dangerous. In my text book, it is written that the peak value of AC is greater than that of DC, which is why it tends to be dangerous. Some people in other forums were saying that DC will hold you, since it doesn't have zero crossing like that of AC. Many others also say that our heart tries to beat with the frequency of ac which the heart cannot support leading to people's death. What is the actual thing that matters most?

After all, which is more dangerous? AC or DC?

I hope it help you..
