Q3W5 NATURE OF ELECTRICITY

What is electricity?

• Energy stored in atoms

• The movement of electrons from one place to another

• A type of magnetic force

• Energy stored in circuits

What are the main components of an atom?

• Electrons, photons, and particles

• Neutrons, protons, and electrons

• Electrons, waves, and protons

• Charges, atoms, and molecules

What happens when a positively charged object meets a negatively charged object?

• They repel each other

• Electrons move between them until they are neutral

• They form new particles

• No reaction occurs

What is the flow of electrons called?

• Electric force

• Electric motion

• Electric current

• Electric power

What is an electric circuit?

• A form of energy transfer

• A complete path through which electric charges can flow

• A device used to store electric charges

• A system that breaks electric connections

What kind of materials conduct electricity?

• Insulators

• Semi-insulators

• Conductors

• Metals only

What happens in a series circuit?

• Each device has its own separate path for current

• Electric current stops at every device

• The end of one device connects to the beginning of the next

• Current flows randomly between devices

What happens in a parallel circuit?

• Electric current flows in a single path

• The same terminals of devices are connected together

• Current does not flow through every device

• Current flows only to one device at a time

What is the role of an electrical insulator?

• To allow electricity to flow freely

• To convert electricity into another form of energy

• To prevent electricity from passing through

• To produce electric current

What determines whether a circuit is closed or open?

• The type of materials used

• The presence of insulators

• Whether the path for current flow is complete or incomplete

• The length of the circuit
