Homework Help: Lethal question

  1. Mar 4, 2006 #1
    Which one is more lethal?
    AC or DC.
    The value of AC rms is given to be equal to DC.
    I think it ought to be DC because it would provide constant voltage. but in case of ac it drops to zero sometimes. I would have exprimented but..... :rofl:

    Think about what is dangerous. Is it the voltage or the current that kills you?

    I don't know what this question is specifically asking? Dead is dead, no matter what killed you...

    The van der graff generator kids play with in high school uses thousands of volts with a tiny current.

    Certain AC current levels cause heart fibrilation (higher levels cause a heart contraction and release,as in a de-fibrilator, not fibrilation) , if the current passes through the heart. That is what usually does the killing. DC is way safer in comparison.
