LISTRIK STATIS

STATIC ELECTRICITY

1.      material
• The balloon or a plastic comb
  Pieces of paper are very small in size
• wool fabrics, silk fabrics etc.

2.      Steps Work

·      Rub a plastic comb with a cloth or rub it on your hair and rub the balloon fabric also performed in one direction repeatedly.

·      Put a balloon that has been rubbed the small kepotongan paper.

·       Observe what happens

 

What happens to the small pieces of paper when approached by an electrically charged balloon?

The electric charge is at rest (static), because that is referred to as static electricity. Static electricity is the energy possessed by electrically charged objects. Electric charge possessed objects that could negatively or positively charged. All objects made ​​of atoms. Each atom has a nucleus composed of protons and electrons that surround it. Protons have a positive electrical charge and electrons have a negative electrical charge are attracted little paper and attached to the balloon because the balloon that has been rubbed on wool fabric SIFA will change it from object to object neutral electricity for a number of electrons that have been transferred by the fabric wool.balloon / comb went through excess electron charge (eloctron more than the proton charge) so that the electrical properties appear on the balloon and its tendency to attract protons neutral objects (small paper).
.

question: How are the mass of comb / balloon after rubbed on fabric / wool?
