How does a lightning rod work?

  1. Aug 13, 2014 #1
    Greetings community

    An engineer came to me seeking help today. He asked me to determining the height of a lightning rod If the radius of the protection zone was given.

    Assuming the roof of the building is completely flat, what would the height (h = ?) have to be for a given radius of 75 meters (r = 75m)?
