Grade 5 Physics Quiz: Circuits

What is the main difference between series and parallel circuits?

• The main difference is the flow of current through the components.

• The main difference is the temperature of the circuits.

• The main difference is the color of the wires used.

• The main difference is the size of the components used.

Explain why series circuits are not commonly used in household wiring.

• Series circuits are safer for household use

• If one component fails, the entire circuit is disrupted.

• Series circuits are easier to install

• Series circuits are more energy efficient

What are examples of good conductors and insulators?

• Wood and plastic

• Copper and glass

• Silver and paper

• Metals and rubber

Why is rubber a good insulator?

• It is a good conductor of electricity.

• It is a good conductor of heat.

• It does not conduct electricity well.

• It is transparent to light.

What happens in a circuit when the switch is open?

• The light bulb gets brighter

• The flow of electricity is interrupted and the circuit is incomplete.

• The circuit becomes more efficient

• The flow of electricity increases

Explain the concept of a closed circuit.

• A closed circuit is a term used in sports to describe a game with no spectators

• A closed circuit is a type of open loop system

• A closed circuit is a pathway for water to flow through

• A complete loop or pathway that allows electricity to flow through it.

In which direction does the electricity flow in a circuit?

• It flows in both directions

• From positive to negative

• From negative to positive

• It doesn't flow in any direction

What is the role of a resistor in a circuit?

• Generates magnetic field in the circuit

• Limits the flow of electric current

• Creates light in the circuit

• Increases the flow of electric current

Name two simple circuit components and explain their functions.

• resistor and capacitor

• transistor and fuse

• inductor and diode

• battery and switch

What is the purpose of a switch in a circuit?

• To cook food in the circuit

• To play music in the circuit

• To open or close the circuit

• To make the circuit colorful
