How can the Wimshurst machine generate a very HIGH voltage?

Click For Summary
SUMMARY

The Wimshurst machine can generate up to 1,000,000 volts despite its compact size of 50 cm. This high voltage is achieved through the accumulation of electric charges in Leyden jars, which act as capacitors. The charges originate from the machine's aluminum foils and are influenced by the neutralizing brushes. Understanding the mechanics of charge accumulation is essential for comprehending the operation of the Wimshurst machine.

PREREQUISITES
  • Basic understanding of electrostatics
  • Familiarity with Leyden jars and their function as capacitors
  • Knowledge of charge generation mechanisms in electrostatic machines
  • Concept of electric potential and voltage
NEXT STEPS
  • Research the principles of electrostatics and charge accumulation
  • Study the construction and operation of Leyden jars
  • Explore the mechanics of the Wimshurst machine in detail
  • Investigate the role of neutralizing brushes in electrostatic machines
USEFUL FOR

Students of physics, educators in electrostatics, hobbyists building electrostatic machines, and anyone interested in high-voltage generation techniques.

It is so surprising that athe Wimshurst machine can generate up tp 1,000,000 voltage with the size of 50 cm!

As I know, in order to generate such a high voltage on its 2 terminals, there must be a very large quantity of charges being "collected and stored" in the Leyden Jars.

Am I right?

If this is true, where are the charges from?
The aluminium foils?
or the "neutralizing brushes?"

Thanks!

Voltage is akin to water pressure. Current is akin to water flow. But instead of water we're talking about "charge". And charge is actually quite a slippery thing to get a grasp of. In one respect all matter is made out of it, so there's plenty of it sitting unnoticed in the mica of the Wimshurst machine. I can't give you a detailed answer about the latter, sorry, but here's a link:
