Electricity and circuits

Electricity is:

• The flow of atoms in a material

• The flow of electrons through a wire

• Light energy flowing through a bulb

Electrons can flow freely through all materials. True or false?

• True

• False

A gap in the circuit:

• Prevents the flow of electrons through the circuit causing the light bulb to switch on

• Still allows the electrons to flow through the circuit and the light bulb still switches off

• Prevents the flow of electrons through a circuit causing the light bulb to switch off

• A, B

• A, C

• C, E, F

• C, D, E
