Explaining Static Electricity

Multiple Choice

Which of the following is an example of conductor?

• rubber

• metal spoon

Multiple Choice

A conductor

• Doesn't allow electricity to pass through it

• Only conducts electricity in an open circuit

• Does not light up a bulb if attached to a circuit

• Allows electricity to pass through it

Multiple Choice

In an insulator, electrons transfer from atom to atom to allow electricity to pass through a wire

• True

• False

Multiple Choice

Why are the wires of a toaster coated in plastic?

• Plastic is stronger than other materials

• Plastic is a good electrical conductor

• Plastic protects people from electricity because it is an insulator

• Only plastic can be made into the right shape of a wire

Multiple Choice

The best insulators are

• Plastic, rubber, wood, glass

• Silver, air, paper, silicon

• Copper, aluminium, gold, steel

• Ceramic, fabric, paper clip, cork

Multiple Choice

A conductor

• Is usually a metal

• Conducts heat

• Can be a copper wire

• All of the above

Multiple Choice

What is a example of a conductor?

• wood 
• metal
• rubber
• rock

Multiple Choice

Charging by rubbing is due to -

• Friction

• Induction

• Conduction

• Contact

Multiple Choice

During a lab a balloon was rubbed with a wooly fabric. This is an example of which type of charging?

• conduction

• friction

• induction

Multiple Choice

Ms Pippin rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?

• The balloons will repel each other.

• The balloons will attract each other.

• The balloons will become positively (+) charged.

• The balloons will pop.

Multiple Choice

An object becomes positively charged by

• losing protons

• gaining electrons

• losing electrons

• gaining protons

Multiple Choice

An object becomes negatively charged by

• losing protons

• gaining electrons

• losing electrons

• gaining protons

Multiple Select

Transferring a charge without touching is

• Induction

• Friction

• Polarization

• None of the above

Multiple Select

Charging by induction is when

• A neutral object is charged by proximity to a charged object

• A static build up of electrons quickly being discharged

• No movement of electrons

• Two objects rub together

Multiple Choice

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

• friction.

• convection.

• induction.

• conduction.

Multiple Choice

A charged balloon is brought near an electroscope but DOES NOT touch the electroscope. This is an example of charging by

• Conduction

• Convection

• Friction

• Induction
