How can the Wimshurst machine generate a very HIGH voltage?

In summary, the Wimshurst machine is capable of generating up to 1,000,000 volts with a size of only 50 cm. This is achieved by collecting and storing a large quantity of charges in the Leyden Jars. The source of these charges is from matter, which is present in the mica of the machine. A more detailed explanation can be found in the provided links.

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:

The Wimshurst machine is able to generate a very high voltage through a process known as electrostatic induction. This involves the transfer of electrons from one object to another, resulting in a buildup of electric charge. In the case of the Wimshurst machine, the two Leyden jars act as capacitors, storing the electric charge that is generated by the machine.

The charges come from the aluminum foils, which are constantly being rubbed against the rotating disks. This friction creates a buildup of static electricity, which is then transferred to the Leyden jars. The neutralizing brushes help to prevent the buildup of too much charge, ensuring that the machine can continue to generate a steady high voltage.

The size of the machine does play a role in its ability to generate such a high voltage. The larger the machine, the larger the surface area of the disks and the more friction that can be created, resulting in a higher charge buildup.

Overall, the Wimshurst machine is a fascinating example of how electrostatic induction can be used to generate high voltages. It demonstrates the principles of electricity and magnetism and has been used in various experiments and demonstrations in the field of science.
 

FAQ: How can the Wimshurst machine generate a very HIGH voltage?

How does the Wimshurst machine generate such a high voltage?

The Wimshurst machine uses two rotating discs with metal sectors and metal brushes to create an electrostatic charge. This charge is then transferred to Leyden jars, which store the charge and can be discharged to generate a high voltage.

What is the maximum voltage that a Wimshurst machine can generate?

The maximum voltage that a Wimshurst machine can generate depends on various factors such as the size of the machine, the speed of the rotating discs, and the humidity of the air. However, it is possible to generate voltages as high as 100,000 volts or more.

Can the Wimshurst machine generate a continuous high voltage?

No, the Wimshurst machine can only generate high voltage in short bursts. As the charge is transferred to the Leyden jars, the machine needs time to build up another charge before it can discharge again.

How is the voltage controlled in a Wimshurst machine?

The voltage in a Wimshurst machine can be controlled by adjusting the speed of the rotating discs. Slower rotation will result in a lower voltage, while faster rotation will result in a higher voltage.

Is the Wimshurst machine safe to use?

The Wimshurst machine can generate high voltage, so caution should be taken when using it. It is recommended to use safety equipment such as gloves and goggles when operating the machine. Additionally, the machine should be grounded to prevent electric shock.
