Golden Earth
Golden Leaf electroscope?

Hello everyone. I'm in yr11 and we are currently studying electricity, mostly static. We experimented on the gold leaf electroscope and "earthing" and about positive and negative charges with plastic rods. If Please can someone explain this experience to me! I do not understand. I know that the plastic rod has a negative charge and the thing plaque Metal has no overall charge. but the rest becomes confused. please explain me in simple terms, the GI in the set-top GCSE Physics. If Please help! thank you very much. X

All things that you come into contact with atoms. They consist of the nucleus is positively charged and electrons which are negatively charged. Normally, these two charges are equal and cancel each other way. Positive and negative charges attract each the other, but the same charges push each other apart, similar to how the poles on the magnets work, north and south but attract the south and repel others. When you rub one against another section, you can rub some electrons on one section and another, how they go depends on the materials you use. Materials that conduct electricity allowing the electrons move through them easily. Materials that do not let them move easily are insulated or non-drivers. If you rub a driver electrons then move in to replace easily those who are rubbed off. This means that it is difficult for drivers to carry a static load. Plastic rod is not a conductor. If you rub with a cloth that easily loose their electrons, they stick to the surface of the plastic rod, because they can not move easily on it. These electrons additional mean that the bar has more negative charge than positive charge. So if you put the plastic rod loaded next to something that makes Then because the charges as electrons are trying to push him out, they will move on the driver, a bit like the opening of the neck with a balloon and let air. Once they are both the insulation and the conductor and the two are charged the same amount, they stop moving. If the driver is an electroscope gold leaf, while the extra electrons will be distributed evenly over the driver. As indicated previously electrons attempt to move away from each other because they have the same negative charge. This means that the ones on the gold foil attempt away from the rest of the metal and in doing so they raise the leaf. Once the leaf electroscope gold is grounded you give these extra electrons to another place to go to get away from each other. They stretch as much as they can be visiting the earth. This means that there is not enough left on the gold leaf to the curb and thus we will withdraw. If you have a stem of a material that can easily go of its electrons then it is positively charged. This will make it more attractive for electrons. If she can not draw the Moreover electrons to replace those he lost. If you put it near the electroscope gold leaf it will draw some electrons away from it. This means that the atoms on the sheet will become positively charged and the paper will try to escape to other atoms positively charged and thus to revolt. If you ground the electroscope now, then it will draw some electrons from the earth to balance its load and the leaf grave.
