Writing electroscope G2

In the cultural week we made an electroscope  with: aluminum foil, copper wire, a glass jar and cork.

How does it work ?

When we approach a charged object to the object we have created, the negative charges are oriented to the top and the positive to the lower. As the charges are the same, the sheets repel, each other indicating that that element has an electrostatic charge.

To verify its operation we have tested with different objects.

For example a loaded balloon that we have rubbed in a sweater, and  we can confirm that this project works .

How does it work

When we approach a charged object to the electroscope, the negative charges are oriented to the top, while the positive ones go towards the bottom of the apparatus. As the charges are the same, the aluminium foils are repelled away from each other, indicating that  element is electrostatically charged. In this way, our home electroscope works, now only remains to test it with different objects to verify its operation.

When an electroscope is charged with a known sign, the type of electric charge of an object can be determined by approaching the sphere. If the lamellas are separated it means that the object is loaded with the same type of charge as the electroscope. Otherwise, if they come together, the object and the electroscope have opposing signs. By measuring the distance at which these conductors are separated can calculate the amount of charge of the body.
