    Arc Flash rules of thumb question is broken

    The question is worded:

    Which of the following is not a rule of thumb when concerning arc flash:
    a. Incident energy decreased by the inverse square of the distance
    b. Incident energy is proportional to time
    c. Each layer of clothing under arc-rated reduces the heat to the body by 50%
    d. Incident energy is inversely proportional to the short circuit current

    D is the correct answer as incident energy is directly proportional to the short circuit current. THe question doesn't like that answer though
