Static charges are electric charges that are produced by rubbing two objects together. When two objects are rubbed together, the friction between them causes electrons to transfer from one object to the other. This transfer of electrons creates an imbalance of electric charges, resulting in the production of static charges.

How static charges are produced
When two objects are rubbed together, the friction between them causes the outermost electrons of one object to be transferred to the other object. This transfer of electrons creates an excess of electrons on one object, giving it a negative charge, and a deficit of electrons on the other object, giving it a positive charge. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. These charges are known as static charges because they do not move or flow through a conductor.

Examples of static charges
Static charges can be observed in various everyday situations. Some examples include:

- Rubbing a balloon on a sweater and then sticking it to a wall.
- Rubbing a plastic comb through dry hair and then attracting small pieces of paper.
- Rubbing a glass rod with a silk cloth and then using it to attract small pieces of paper.

Characteristics of static charges
Static charges have several characteristics that distinguish them from other types of electric charges:

- They are produced by rubbing two objects together.
- They do not move or flow through a conductor.
- They can attract or repel other charged objects.
- They can cause objects to stick together or cling to surfaces.

Conclusion
In conclusion, the electric charges produced by rubbing two objects together are known as static charges. These charges are created through the transfer of electrons between the objects, resulting in an imbalance of electric charges. Static charges can be observed in various everyday situations and have distinct characteristics that differentiate them from other types of electric charges.
