There are three
ways to give the electric charge:
1. How to scrub
2. How conduction
3. How induction
1. Electrostatic Discharge Giving Ways Rubbing
Rubbing separates the charge, causing the balloon is negatively charged and positively charged wool fabrics
At first, both balloon and wool fabric has a neutral charge. After rubbing, electrons flow from wool cloth into balloon. The balloon becomes electrified negative, it gets an additional electron. (Number of electrons greater than the number of protons). Wool fabric becomes positively charged because of the number of electrons less than the number of protons.
Types of electric charges obtained by rubbing two different types of objects.
- Plastics and ebonite will negatively electrically charged when rubbed with a woolen cloth
- Glass will be positively charged when rubbed with silk cloth
2. Electrostatic Discharge Giving Ways Conduction
In the event of conduction, the direct contact of two objects so that electrons flow through one object to another object.
A metal can be a negative electrical charge (a) positive or (b) by way of conduction
Some materials are classified as conductors and insulators
a. Conductor
- Conductor either: different types of metals (silver, copper, metal)
- Conductor ugly: water, earth, the human body
b. Isolator: rubber, various plastics (PVC, politen, perspeks)
In the materials considered insulators, electrons per atom bound with strong, so under normal circumstances, the electrons are not free to move. As a result, the insulator material is difficult to conduct an electrical charge.
2. Electrostatic Discharge Giving Ways Induction
Electric Induction is the separation of electric charge in a conductor as the conductor was approached by (without touching) electrically charged objects.
Example:
A balloon that has been rubbed on someone's hair touched to a neutral wall and found the balloon still attached to the wall.
What is the process?
Consider the following figure.
Balloon that has been rubbed against the wall
Balloon that has been rubbed on someone's hair would negatively charged, while the walls initially neutral [image (a)]. When the balloon approached the wall, then the electrons are negatively charged wall turned away from the balloon. Consequently the walls in contact with the balloon positive polarity. This causes the balloon can stick long enough on the wall [image (b)].
The working principle of electrical induction, the basis for the creation electroscope. Electroscope is a device that is used to determine an object electrically charged or not.
