Electricity

What is a conductor?

• A material that allows the flow of electric current.

• A material or device that does not conduct electricity

• A type of musical director

• A type of insulator

Give an example of a good conductor of electricity.

• Copper

• Glass

• Plastic

• Wood

What is an insulator?

• A device that generates electricity

• A type of battery used in electronics

• A material or device that does not conduct electricity.

• A material that conducts electricity very well

Provide an example of an insulator.

• Rubber

• Gold

• Glass

• Metal

What is the function of a battery in an electrical circuit?

• It transport electric currents from one point to another

• It provides mechanical energy to the circuit

• It generates heat in the circuit

• It is the source of power in the circuit

Explain the purpose of a switch in an electrical circuit.

• To open or close the circuit and control the flow of electricity.

• To store electricity

• To generate electricity

• To measure electricity

What is a series circuit?

• A circuit in which the components are connected in a single path for the flow of electric current.

• A circuit in which the components are connected in a random pattern for the flow of electric current.

• A circuit in which the components are connected in multiple paths for the flow of electric current.

• A circuit in which the components are not connected to each other.

How does a parallel circuit differ from a series circuit?

• The current has multiple paths to flow through in a parallel circuit.

• The current has only one path to flow through in a parallel circuit.

• A parallel circuit has a higher resistance than a series circuit.

• In a parallel circuit, the voltage is the same across all components.

In a series circuit, what happens if one bulb goes out?

• All the bulbs will go out

• The other bulbs will get brighter

• The other bulbs will flicker

• The other bulbs will stay the same brightness

In a parallel circuit, what happens if one bulb goes out?

• The circuit will explode

• The electricity will stop flowing

• The other bulbs will continue to shine

• The other bulbs will also go out
