Static Electricity GPB Video

What is static electricity?

• A type of electricity that powers vehicles

• The accumulation of electric charge on the surface of, or within, a material

• The discharge of electric charge during a thunderstorm

• The movement of electric charge through a conductor

What happens when static electricity is discharged from an object?

• Electrons move and are released or discharged from the object

• It increases the object's mass

• It creates a permanent electric field around the object

• It causes the object to become magnetized

How do electrostatic sprayers in car painting work?

• By heating the paint to a high temperature

• By charging the paint particles with extra electrons

• By using magnetic fields to direct the paint

• By applying a high-pressure spray

What is the charge of a proton?

• Positive

• Neutral

• Variable

• Negative

What is the charge of an electron?

• Positive

• Neutral

• Negative

• Variable

What is the principle behind charging by friction?

• Transferring charge by direct contact

• Charging an object by bringing a charged object close to it

• Rubbing two materials together to transfer electrons

• Using a chemical reaction to create charge

What is an electroscope used for?

• Converting electrical energy into mechanical energy

• Detecting magnetic fields

• Showing how charge accumulates

• Measuring the speed of electrons

What is induction in terms of static electricity?

• Transferring charge through a vacuum

• Charging an object by bringing a charged object close to it but not touching

• Creating a charge by splitting atoms

• Charging an object by heating it

What does the Law of Conservation of Charge state?

• Electric charge can be created but not destroyed

• Electric charge is always conserved in a closed system

• Electric charge can be destroyed but not created

• Electric charge can neither be created nor destroyed

What is the role of electrostatic precipitators in industrial plants?

• To capture dirt particles on a positively charged plate

• To reduce friction in machinery

• To cool down the machinery

• To generate electricity
