11THg IGCSE Electricity Quizizz

A man pushes a metal trolley along a corridor towards a lift. The trolley has nylon wheels and the floor of the corridor is covered with plastic. The man wears shoes with rubber soles. As he moves the trolley, the man gains an electric charge.

Which choice indicates how the man gains an electric charge.

• Transfer of protons due to force between floor and lift

• Transfer of electrons due to force between shoes and wheel

• Transfer of electrons due to friction between floor and shoes

• The man doesn’t gain an electric charge.

When a plastic rod is rubbed with a cloth, the rod gains charge.

How could you show that the plastic rod gains charge?

• Use charged object to check

• Attract scraps of paper

• Deflect water stream

• You cannot show plastic rod gains charge

When a plastic rod is rubbed with a cloth, the rod gains charge. There are two types of charge.

Which choice shows how you could demonstrate this using different insulating rods and a cloth?

• Cannot charge rods and does not have any using.

• Charge rods and use charged gold leaf electroscope (GLE) and look for rise and fall of leaves

• Rubbing with the cloth as charging by force

• Using of charge rods and suspend it to observe for rise and fall.

A car becomes electrically charged as it travels along a road.

Which choice indicates how a moving car becomes electrically charged.

• Reaction force between car and ground where electron transfer occur

• Friction between car and ground where proton transfer occur

• No force or friction present, but electron transfer occur

• Friction between car and ground where electron transfer occur

Give an example of a device that uses Static Electricity

• Laundry Machine

• Vacuum Cleaner

• Photocopier

• Loudspeakers

Why is the paper heated in a photocopier?

• to make the text appear

• to make the powder stick

• to make sure the electrons are absorbed

• to discharge the paper

How does static electricity work in lighting?

• the raindrops and ice bump together inside the cloud, making the top of the cloud positive and the bottom negatively charged, creating a huge voltage

• the ice and dust in the cloud bump inside the clouds, making electrons fall onto the ground

• the negative electrons repel each other, creating a huge spark

• A current travels from the cloud into earth.

What do we need to do to prevent the ‘Fuel-Filling Nightmare’?

• make the nozzle out of metal

• have an earthing strap between the fuel tank and the fuel pipe

• Discharge all static electricity away by touching a metal surface before you fuel gas

• All of the above

In an inkjet printer, how are the droplets able to hit a different place on the paper?

• the plates move

• the current in the place changes

• The resistance in the plate changes

• the size and direction of the voltage across each plate changes

This table gives some information about a nuclear power plant and a wind turbine. Using the data from the table, calculate the number of wind turbines needed to produce the same power as a nuclear power station.

• 100.0

• 10.00

• 10 000

• 1000.00
