Circuits & Electricity 5th Grade

What is a fuse?

• A device that amplifies electrical signals.

• A safety device that protects a circuit by breaking the connection if the current exceeds a certain level.

• A type of resistor used to limit current flow.

• A switch that controls the flow of electricity in a circuit.

What is an open circuit?

• A circuit that allows current to flow continuously.

• A broken circuit where the current cannot flow due to a gap or break in the path.

• A circuit that has a short circuit causing excess current flow.

• A circuit that is completely closed and operational.

What is the function of a light bulb in a circuit?

• A light bulb converts electrical energy into light energy when current flows through it.

• A light bulb stores electrical energy for later use.

• A light bulb increases the voltage in a circuit.

• A light bulb acts as a resistor to limit current flow.

What is resistance in an electrical circuit?

• A measure of how much a material opposes the flow of electric current, often measured in ohms.

• The ability of a material to conduct electric current without any opposition.

• The total amount of electric current flowing through a circuit at any given time.

• A type of electrical component that stores energy in an electric field.

What materials are considered insulators?

• Rubber, glass, plastic, and wood

• Copper, aluminum, steel, and iron

• Water, mercury, ethanol, and acetone

• Concrete, brick, stone, and metal

What is a closed circuit?

• A circuit that is open and allows no current to flow.

• A complete electrical circuit through which current can flow without interruption.

• A circuit that only works with batteries and not with mains electricity.

• A circuit that has multiple paths for current to flow.

What is a parallel circuit?

• A type of circuit where current flows in a single path.

• A type of circuit where there are multiple paths for the current to flow.

• A circuit that only works with alternating current.

• A circuit that has no resistance.

What is a series circuit?

• A type of circuit where components are connected in parallel, allowing multiple paths for current.

• A type of electrical circuit where the components are connected end-to-end, so the current flows through each component in turn.

• A circuit that only allows current to flow in one direction, typically used in diodes.

• A circuit that has no components connected, resulting in an open circuit.

What is an insulator?

• A material that allows electricity to flow easily, such as copper.

• A material that does not allow electricity to flow through it easily, such as rubber, glass, or plastic.

• A device that stores electrical energy for later use.

• A type of conductor that enhances electrical flow.

What happens when a circuit is incomplete?

• The flow of electricity continues, and devices work normally.

• The flow of electricity stops, and devices connected to the circuit will not work.

• The circuit becomes overloaded, causing devices to malfunction.

• The circuit generates excess heat, damaging the devices.
