Question

How does rubbing one object on another create static electricity?

Answer 1

Static electricity is the phenomenon in which the charged particles are transferred from one body to another body. Static electricity is the electricity that is built up on the surface of the substance.

Complete step by step answer:
Whenever an object is rubbed over another object, static electricity is created. This is due to the reason that rubbing creates a negative charge which is carried by the electrons. These electrons will build up to produce static electricity.
So when we rub one object on the object, the electrons are transferred from one object to the object. Then these two objects will attract each other as the electrostatic force between them with the opposite charge is attractive. Thus one object becomes positively charged by losing the electrons and the other object becomes negatively charged by gaining the electrons.

Additional Information:
1. The static electricity does not induce the magnetic field.
2. Static electricity can be measured by using a Gold Leaf Electroscope.
3.The examples of static electricity are Lightning strokes developed due to the rubbing of the balloons on the hair.
4. We can turn Static electricity into current electricity.

Note:
1. The three methods by which the charges can be transferred to build-up static electricity are conduction, induction, and charging by friction.
2. In friction, rubbing the two surfaces transfers the electrons from one object to other objects. In conduction, the electrons will flow freely from one object to another object.
3. The static electricity is developed in both the conductor and the insulator.
