Complete the sentence: An electrical insulator is a material which
allows electrons to flow through easily.
has delocalised electrons.
does not allow electrons to flow through easily.
is used for wires in an electrical circuit.
How can an insulator be charged?
by placing it into a circuit
by rubbing it with a cloth
by connecting it to the mains
none of the above
A plastic rod can be given a negative charge by rubbing it with a cloth. Which of the following statements is correct?
The protons move from the rod to the cloth.
The protons move from the cloth to the rod.
The electrons move from the cloth to the rod.
The electrons move from the rod to the cloth.
If two free hanging rods with the same charge are brought together, what will happen?
The rods will move away from one another.
The rods will move towards one another.
The rods will not move.
The rods will discharge.
A student is insulated and places her hands on a Van der Graaf generator. Which of the statements explains why the student’s hair stands on end?
The hairs have the same charge and are repelling each other.
There is a current flowing through the hair.
The student is receiving an electric shock.
The hairs have opposite charge to the skin.
A gold leaf electroscope is uncharged. What will happen if a negatively charged polyethene rod is brought towards the top plate?
The rod will repel the positive charges down to the bottom of the electroscope.
The gold leaf will become positively charged.
The gold leaf will become negatively charged.
Negative electrons will rise to the surface of the metal plate.
A lightning cloud has a high negative charge towards the bottom of the cloud. Which of the statements explains what will happen to the ground below the cloud?
Positive charges in the ground will move to the surface, making it positive.
The electrons from the cloud will jump to the ground and make the ground negative.
Negative charges in the ground are repelled away by the cloud leaving positive charges on the ground’s surface.
The ground remains neutral in charge.
Which statement correctly describes how a conductor can become statically charged?
The conductor is isolated from earth and a charged insulator is brought near to it.
A conductor is connected to the mains.
The conductor is touched by a charged insulator.
A conductor cannot be statically charged.
Which of the following statements is an advantage of using an electrostatic paint sprayer to paint an object?
The paint forms a thin even layer over the object.
The paint is attracted to the surface of the object so less paint is wasted.
The paint is attracted to hard-to-reach areas of the object.
All of the above.
In a photocopier, a toner drum is positively charged. Which of the following statements best describes how ink is applied to the drum.
A heater binds the ink to the toner drum.
Negatively charged ink is attracted to positively charged parts of the toner drum.
Positively charged ink is repelled from the toner drum onto the paper.
The ink has no charge and is sprayed onto the toner drum.
What is the role of an electrostatic precipitator in a power station?
to remove smoke from chimneys
to remove ash and dust from smoke in chimneys
to charge the smoke coming out of the chimney
to remove charges from the air
Why do helicopters have to earth themselves with a conductor when they land?
They become charged because of friction with the air when in flight.
They need to allow excess charge to flow to the ground.
To prevent sparks when refuelling.
All of the above.
Planes need to be earthed when they return to ground before refuelling. Which statement correctly describes the term earthing?
It allows negative charge to flow away from the aircraft so it is no longer charged.
It allows the plane to be connected to the ground.
It allows positive charges to flow up to the aircraft to balance out its charge.
It allows fuel in the aircraft to discharge.
Why does an inkjet printer use electrostatic charges?
to make ink stick to paper
to direct a fine beam of ink to the correct place on a sheet of paper
to clean away excess toner
to provide an electric current
