Technical data Electrostatic tip-shape effectItem No. P6005400 Principle A lightning forms a strong electric current, which is created, when in a medium (for example air) a large number of free charges is produced by strong electric fields. During a thunderstorm usually high elevations from earth (for example skyscrapers) are more often affected by lightning strokes. Benefits
Tasks
Learning objectives With this experiment the students will investigate how a lightning is created during a thunderstorm and why elevations from the earth such as skyscrapers have a higher risk of being struck. In the experiment the students will simulate the electric field between a thundercloud and the earth ground by two parallel rod electrodes. One of the electrodes contains a tip-shape electrode, which changes the homogeneous electric field the same way a skyscraper will change the field between thundercloud and earth ground.
