Static Electricity Quiz

What is static electricity?

• The flow of electric current through a conductor

• A separation of charge caused by the movement of electrons from one material to another

• The resistance of a material to the flow of electric current

What is triboelectric charging?

• The flow of electric charge through a conductor

• The transfer of electrons between two or more dissimilar materials resulting in static charging

• The ability of a material to resist the flow of electric current

What determines the nature and size of the charge produced by static electricity?

• The resistance of the materials

• The ability of the materials to conduct electricity

• The ease with which the materials lose or gain electrons

Which of the following is an example of static electricity?

• The flow of electric current through a light bulb

• The movement of electrons through a wire

• The shock you get when touching a door handle after walking across a carpet

Why is triboelectric charging important in the design of aircraft and aircraft furnishings and equipment?

• Because it can cause a fire hazard

• Because it can interfere with electronic equipment

• Because it can affect the comfort and safety of passengers and crew

What is the difference between a neutral material and a charged material?

• A neutral material has no electrons, while a charged material has electrons

• A neutral material has equal numbers of positive and negative charges, while a charged material has an excess of one type of charge

• A neutral material conducts electricity, while a charged material does not

If two materials are rubbed together and one obtains a positive charge, what charge will the other material obtain?

• A positive charge

• A negative charge

• No charge

If a glass rod is rubbed with human skin, what charge will the rod obtain?

• A positive charge

• A negative charge

• No charge

What happens to the charge when a conductor is charged by rubbing?

• The charge remains at the point of friction

• The charge dissipates

• The charge moves freely through the material

How is the electric field around a charged body represented?

• By magnetic lines of force

• By electric lines of force

• By gravitational lines of force
