  I don’t need to, because I know how electrical circuits work. I don’t think you do. But, go on, explain why I’m wrong.

    I didn’t know I was talking to a professional here!

    what would be the resistance of a plate of 16 gauge aluminum over 9 feet long?

      I’ll answer that for you, but first tell me what the (typical, average, ballpark) resistance of a human body is.

        totally depends on conditions.

        for a typical dry adult hand with a moderate to heavy amount of calloused skin, it’s around 100k Ω. add any type of moisture or water like sweat it will be far less.

        btw did you know the skin is the primary conduit of electrical conductively? only HV is a real danger to your organs because it permeates through all tissue.

        side note. the internal resistance of the human body sits around 200-400 Ω.

        so, what’s the resistance of a 16 gauge plate of aluminum that’s 9 feet long? in all honesty it’s probably more likely to be 22 gauge though. which one would have the lower resistance?
