WIMSHURST MACHINE

This is the Wimshurst machine.
It is a machine to obtain high voltages that let you carry out electrostatic experiments.
It consists of two plastic discs that rotate in opposite directions when a lever is turn.
On each disc there are metal sheets, which can be made of copper, tin or aluminum.
Discs can rotate in opposite directions because one tape is set to the right and the other to the reverse.
There are four metal springs in contact with the discs that are loaded by friction.
The charge reaches an area where another charge is induced, without contact.
The induced charge is stored in two accumulators called Leyden jars.
One bottle is positively charged and the other one negatively.
When the lever is turned, the discs rotate, the Leyden jars are charged, and when the accumulated charge is high enough, the air becomes conductive and sparks fly between the metal spheres.
