Static electricity Examples

What is Static Electricity:

Static electricity is an electric charge that has built-up on an object.It is often created when two objects that are poor electrical conductors are rubbed together. The electrons of one object rub of onto another.


Static electricity Examples:


Picture 1:


In this picture a balloon is rubbed to a persons hair and in this case static electricity is caused which is why the child's hair went up towards the balloon and this is caused by the building of electrical charges since the hair and the balloon are poor conductors. 


















Picture 2:


This picture shows a person being shocked by a doorknob with a cause of static electricity. this is caused by the person and it is a small spark that can  jump from your finger to some metal object, giving you a slight shock. this type of shock is the most common one that people experience.














Picture 3: 
  
This picture shows lightning which is the largest spark of static electricity. A lightning bolt can be over 1.5 km or about 1 mile in length. The amount of voltage released in a lightning bolt is typically about 100,000,000 volts, which makes us see it.
