Types of electric charges

Article about the Types of electric charge

Why does plastic repel plastic but attract glass? If you rub a plastic on dry hair and bring the plastic to the small pieces of paper, the plastic pulls the pieces of paper. Why can plastic also pull pieces of paper that were not rubbed with other objects? You will understand and can even explain the reasons for the phenomena experienced by the glass, plastic, pieces of paper or other objects as reviewed above after you learn the topic of electric charges and understand the reviews below.

Plastics that are rubbed with hair pulling glass rubbed with a cloth. Plastics and glass are attractive, so plastic and glass have different electrical charges. If an object repels plastic but pulls glass, it has a similar charge to the charge on the glass. Conversely, if an object repels a glass but pulls a plastic, it has a similar charge to the charge on the plastic.

Benjamin Franklin (1706-1790), a United States statesman and scientist, suggested naming these two types of charge as positive and negative charges.
Furthermore, he named the electric charge as in the glass as a positive charge and the electric charge as in plastic as a negative charge. The charged objects that repel the charged glass must be positively charged because like charges repel each other. On the other hand, charged objects which pull charged glass must be negatively charged because of the unlike charges to attract each other.

Likewise, charged objects which repel charged plastic must be negatively charged because like charges repel each other. On the other hand, charged objects which attract charged plastic must be positively charged because of the unlike charges to attract each other.

How to charge an object

Objects that are initially neutral or not electrically charged can be electrically charged using some ways, which is by friction and by induction.
