The branch of science called xerography makes use of static electricity. It is used in the xerox machines to print or copy documents. In this instrument, there is a special component that charges the particles of ink and helps them accumulate on the sheet. Static electricity is also used in the area of painting the cars.

What is charging?
The gain or loss of electric charge by a material is called charging.
What is the smallest quantity of charge found in nature?
The elementary electric charge, equal to the electric charge of an electron or a proton.
How do objects become electrically charged?
Objects become charged when the total number of positive charges on the object is greater than the totsal number of negative charges or vice versa....
What happens when uncharged objects are brought close to each other?
When uncharged (neutral) objects are brought close to each other, no push or pull of either objects is observed.

How is Static Electricity Created?
We can create a static electric charge by rubbing two surfaces in contact that are at some distance. Also, at least one of the surfaces has a high resistance to electric current (and is, therefore, an electrical insulator).
What happens when lightning strikes a house?
The other end is deeply embedded in the earth. As the lightning strikes, the lightning rods transfer the electrons from the clouds to the earth below. As a consequence, the house is protected from electric current.
How does a static generator work?
A static electricity generator works on the principle of electrostatic induction to generate static electricity. Static electricity has several real-life implications like lightning. It is also used for several daily purposes. 2.
How does electricity flow?
The flow of electrons defines electricity. Electrons flow when there is an imbalance in the electron concentration of two bodies in contact. When there is a contrast in the electrical charges, i.e., the positive and the negative charges in a body, static electricity is generated. As per the static electricity definition, this imbalance of electrical charges is created by physical forces. This is the basic difference between static electricity and current electricity. If you understand the static electricity meaning, you must know that the two bodies have to be in contact. Since protons are located at the centre of the atom, they cannot move. Therefore, the only movement of electrons takes place. This is because electrons located at the outermost orbitals experience lesser attraction from the nucleus and shift to other atoms.
How do rain clouds form?
The opposite movements of hot and cold air result in friction. The flow of electrons takes place due to this friction. As the rain clouds are formed, the top portion carries the maximum positive charges while the bottom parts carry the maximum negative charges. This imbalance in charge distribution increases further when the rain clouds get heavier. This imbalance creates a channel of air through conduction, allowing the flow of charges. This flow of charges visually results in lightning. Lightning is associated with the generation of a large amount of energy. This energy is manifested in the form of thunder.
Why do electrons flow in rain clouds?
The flow of electrons takes place due to this friction. As the rain clouds are formed, the top portion carries the maximum positive charges while the bottom parts carry the maximum negative charges. This imbalance in charge distribution increases further when the rain clouds get heavier.
How is electricity generated?
The electricity is generated due to the imbalance created in the distribution of electrons between the two surfaces. Due to the friction generated due to such movements, the electrons are rearranged on the surface of the two bodies. In this rearrangement process, electrons are transferred from one body to another.
What Is Static Electricity?
Static electricity refers to the accumulation or build-up of electric charge on the surface of an object. It is called static because the electric charge remains constant and does not flow or move.
What are the two parts of an atom that make up the nucleus?
Neutrons and protons make up the nucleus, the center of the atom, while the electrons move around the nucleus. Protons have a positive charge, neutrons are neutral, and electrons have a negative charge. A static charge is generated when two surfaces come in contact, and the electrons get transferred from one surface to another.
How many volts can a spark of static electricity carry?
A spark of static electricity can measure thousands of volts but has very little current and lasts for a short time. 3. A bolt of lightning can carry a voltage of more than 10 million volts. 4. Static electricity can build up faster on a dry and low-humid day.
What is static energy used for?
Photocopiers: Static energy is used in photocopiers to attract the ink powder, known as toner, to the paper. A copier has a special drum that is charged with static energy. This drum attracts the negatively charged toner particles onto paper, forming precise letters or figures.
How does static charge occur?
A static charge is generated when two surfaces come in contact, and the electrons get transferred from one surface to another. In the process, one surface becomes positively charged, and the other surface becomes negatively charged.

Why is the wall of a balloon more positively charged than the surface?
This happens because a surplus of electrons (negative charges) is added to the balloon’s surface , and now the wall is more positively charged than the balloon.
