If a bolt of lightning (MEGA volts at MEGA amps) struck |the lightning rod sitting on a wooden barn or house, you would really be |talking FLAMES. Even if the wire cable that would be carring the current to |ground was low resistance, at that current there would be a LARGE voltage drop |across the cable. The power disapated would heat the cable red hot; not |exactly something you want attached to your wooden structure. How do you account for those real pictures of lightning rods on tall skyscrapers taking hits? Ken
