Homework Help: Transformer problem (falling off of one, that is)

  1. Feb 28, 2010 #1
    1. The problem statement, all variables and given/known data
    Which is more dangerous: the electric shock caused by falling off of a transformer, or the impact when one falls, and why? Also, what would the voltage of a 12ft (meh. might as well go with 4m) transformer be about?


    2. Relevant equations
    V = IR
    U = mgh

    3. The attempt at a solution
    I was considering using a comparison of forces, but then I considered that the timing was off for the two, as the collision happens (nearly) at once, while the shock could take place over a period of time.

    Thanks in advance,
    Statue
    Also, I found that the final velocity should be 8.85 m/s

    It's really impossible to tell how close to a conductor you come if you fall off a transformer,
    what voltage might be on it, and what kind of insulation might protect it.
    Transformers of large high voltage power lines with wires on top fastened to isolaters, can
    kill you from some distance away. (about the size of an isolator). Climbing on top of a live one
    is extremely dangerous.
    Of course you shouldn't be anywhere with the fence built around one of those.
