Why do different materials have different electrical charges?
Furthermore, it was explained that material objects are made of different types of atoms and combinations of atoms. The presence of different atoms in objects provides different objects with different electrical properties.
What happens when an object is electrically charged?
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
How does an electrically polarized object differ from an electrically charged object?
How does an electrically polarized object differ from an electrically charged object? A charged object has a net charge; a polarized object is negative or positive on one side, but its net charge is zero.
What happens when two electrically charged objects get near each other?
Opposite charges attract each other, while like charges repulse each other. When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced.
How does charging by conduction occur?
Describe charging by conduction. A charged object (source) is brought near a neutral object and the neutral object becomes polarized. Then, when the source is brought in contact with the object, electrons are transferred. The neutral object (or ground) is taken away from the other object first.
How does charging processes affects the charges of a certain object?
During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively.
How do you electrically charge an object?
An uncharged object can become charged by gaining or losing electrons. If an object loses electrons, it is left with more protons – giving it an overall positive charge. If an object gains electrons, it will have an overall negative charge. The build-up of charges on an object is called static electricity.
What is a major difference between static electricity and current electricity?
The most significant difference between the static electricity and the current electricity is that in that static electricity the charges are at rest and they are accumulated on the surface of the insulator, whereas, in current electricity the electrons are in state of motion inside the conductor.
How does the charge of one electron compare with the charge of another electron How does it compare with the charge of a proton?
How does the charge of one electron compare to that of another electron? All electrons have the same charge. Electron charge is equal and opposite to the proton charge. A proton has 1800 times the mass of an electron.
How does the charge of an electron compare to the charge of a proton?
Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite.
How do particles with the same charge react?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. Objects with like charge repel each other.
Why do like charges repel each other?
Now, when a positive charge is brought closer to another positive charge, once the virtual transfer of photons occurs, there is an excess number of photons in both the charges, which tend to repel them away from each other. Therefore, like charges repel and unlike charges attract.
