(Physics) - Static Electricity

• What is static electricity?

  Static electricity is the build-up of electrical charge on the surface of objects.
• How does static electricity differ from current electricity?

  Static electricity involves charges that are not flowing through a circuit.
• What causes static electricity to occur?

  Static electricity occurs when certain materials are rubbed together and electrons move from one object to another.
• What is the nature of static electricity?

  Static electricity is a stationary electric charge.
• What results in static electricity?

  Static electricity results from an imbalance of positive and negative charges.
• What can static electricity cause objects to do?

  Static electricity can cause objects to attract or repel each other.
• What are the two types of electric charges?

  The two types of electric charges are positive charge and negative charge.
• How are electric charges measured?

  Electric charges are measured in coulombs (C).
• What happens when like charges are brought close together?

  Like charges repel each other.
• Which type of materials are more likely to build up static charge?

  Insulators are more likely to build up static charge than conductors.
• What happens when opposite charges are brought close together?

  Opposite charges attract each other.
• What charge do electrons carry?

  Electrons carry a negative charge.
• What is one observable effect of static electricity?

  Static electricity can cause attraction and repulsion between charged objects.
• What can happen when the charge difference is large enough?

  Electrons can jump through the air, creating a visible spark.
• What charge do protons carry?

  Protons carry a positive charge.
• What charge do neutrons have?

  Neutrons have no charge.
• What occurs when the balance of protons and electrons is disrupted?

  Static electricity occurs when the balance of protons and electrons is disrupted.
• How is static electricity generated?

  Static electricity is generated through the process of triboelectric charging when certain materials are rubbed together.
• How do air purifiers utilize static electricity?

  Air purifiers use static charge to attract and trap dust particles.
• How do photocopiers and laser printers work with static electricity?

  Photocopiers and laser printers rely on static electricity to attract toner to paper.
• What is the role of friction in generating static electricity?

  Friction between materials causes electron transfer, leading to static electricity.
• What is the triboelectric series?

  The triboelectric series ranks materials by their tendency to gain or lose electrons.
• What is one everyday example of static electricity?

  Static cling in laundry is an everyday example of static electricity.
• What happens when you rub a balloon on your hair?

  Electrons move from your hair to the balloon, leaving your hair positively charged and the balloon negatively charged.
• What happens when you receive a shock after walking on a carpet?

  Electrons transferred from the carpet to your body, then discharged to the doorknob.
• What is an electric shock?

  An electric shock is a sudden discharge of static electricity that can cause a mild shock.
• What are some beneficial effects of static electricity?

  Static electricity can be used in air purifiers and to attract toner in photocopiers.
• What is the cause of paper sheets sticking together in a recycling facility?

  Electrostatic attraction between charged sheets is causing them to stick together.
• What method might a company use to improve car painting efficiency based on static electricity?

  Electrostatically charging the paint particles to attract them to the car's surface.
• What are the key points about how static electricity is generated?

  - Static electricity is generated through triboelectric charging when materials are rubbed together. - Friction causes electron transfer between materials. - Insulators are more likely to build up static charge than conductors. - The triboelectric series ranks materials by their tendency to gain or lose electrons.
• How do lightning rods work in relation to static electricity?

  Lightning rods protect buildings by providing a safe path for lightning, which is a large static discharge, to follow.
• What are the key points about static electricity?

  - Static electricity is a build-up of electrical charge on the surface of objects. - It is a stationary electric charge resulting from an imbalance of positive and negative charges. - It can cause objects to attract or repel each other.
• What are the key points about electric charge?

  - Electric charge is a fundamental property of matter. - There are two types of electric charges: positive and negative. - Charges are measured in coulombs (C). - Like charges repel, opposite charges attract. - Electrons carry negative charge, protons carry positive charge, and neutrons have no charge.
• What are some practical applications of static electricity?

  1. Air purifiers trap dust particles. 2. Photocopiers and laser printers attract toner to paper. 3. Paint spraying ensures even coverage. 4. Dust removal with feather dusters. 5. Lightning rods provide safe paths for lightning.
• What are the observable effects of static electricity?

  1. Attraction and repulsion between charged objects. 2. Sparks from large charge differences. 3. Electric shocks from sudden discharges. 4. Hair standing on end due to repulsion.
