Static Electricity

What is static electricity?

• A build-up of electrical charge on an object

• A flow of electric current through a conductor

• The transfer of heat through a material

• The movement of protons in a circuit

What happens when you rub one neutral, electrically insulating object against another?

• The objects become superconductors

• Protons are transferred between the objects

• The objects become magnetic

• Some of the electrons are transferred across

What type of force is exerted by charged objects on each other?

• Gravitational force

• Electrostatic force

• Magnetic force

• Nuclear force

What is the result when opposite charges are near each other?

• They become neutral

• They repel each other

• They attract each other

• They create a magnetic field

What is the charge of an object that has gained electrons?

• Positively charged

• Neutral

• Negatively charged

• Magnetically charged

What is the charge of an object that has lost electrons?

• Magnetically charged

• Neutral

• Positively charged

• Negatively charged

What is the process called when charges move or separate in a neutral object?

• Conduction

• Polarisation of charge

• Magnetisation

• Ionisation

What is the main reason electrons can be transferred between objects?

• They are positively charged

• They are tightly bound in the nucleus

• They have a high mass

• They have a low mass and are mobile

What happens when like charges are near each other?

• They repel each other

• They attract each other

• They become neutral

• They create a magnetic field

What is an example of a neutral object being attracted by a charged object?

• A magnet attracting iron

• A light bulb lighting up

• A charged balloon sticking to a wall

• A battery powering a device
