Explain What Happens When Amber is Rubbed with Wool or Silk.

When amber is rubbed with silk or wool, the amber becomes positively charged due to static electricity. Charges can be classified as positive and negative charges. Like charges repel each other whereas the unlike charges attract each other. The force between the charges decreases as the distance between them increases.

When a glass rod is rubbed with amber, electrons are transferred from the glass rod to amber leaving it with a slightly greater positive charge and the amber rod acquires a negative charge.

What is static electricity?

Static electricity is an imbalance between the electric charges in a body, specifically the imbalance between negative and positive charges on a body. Static electricity is mainly produced due to the contact between solid objects.

Characteristics of static electricity

The characteristics of static electricity are as follows:

There are two types of charges – positive and negative charge.
Like charges repel each other whereas unlike charges attract each other.
As the distance between charges increases, the force between them decreases.
