Early experimenters would charge the jar using electrostatic generators, and then discharge it with a dramatic spark. The Leyden jar is one of the first devices that allowed humans to store and ...

This Van de Graaf generator was ... rotating belt to generate static electricity. This potential is stored in the metal collecting sphere on top until a path for discharge is provided.

You can discharge a charged object by giving ... electrostatic sparks Machines designed to generate static electricity, like Van de Graaff generators or Wimshurst machines can produce large ...
