Safest place during a Safest place during a lightning storm is in a plane lightning storm is in a plane or car because it is a or car because it is a Faraday CageFaraday Cage

Answer: They form a Answer: They form a Faraday Cage i.e., they Faraday Cage i.e., they are surrounded by metal; are surrounded by metal; if you are surrounded by if you are surrounded by metal you are safe the metal you are safe the electricity flows around electricity flows around the outsidethe outside
