Energy and circuits mini assessment

What is energy?

• Energy is the ability to do work or cause change, and it is what powers electrical devices.

• Energy is a measure of the amount of matter in an object.

• Energy is the force that opposes motion between two surfaces.

• Energy is the temperature of an object.

What is a D cell?

• A type of battery that stores energy and provides power to electrical devices.

• A type of rechargeable battery used in smartphones.

• A type of battery used exclusively in remote controls.

• A type of battery that is only used in flashlights.

What is resistance in a circuit?

• A measure of how much a component opposes the flow of electricity, affecting how much current flows.

• The total amount of voltage in a circuit.

• The speed at which electricity travels through a conductor.

• The amount of power consumed by a device in a circuit.

How does electricity flow in a circuit?

• Electricity flows from the positive terminal of the battery, through the wire and components, and returns to the negative terminal.

• Electricity flows from the negative terminal of the battery, through the wire and components, and returns to the positive terminal.

• Electricity flows only through the components and does not return to the battery.

• Electricity flows in a circular motion without a defined start or end.

What is a series circuit?

• A circuit where components are connected in parallel, allowing different currents to flow through each component.

• A type of circuit where components are connected one after another, so the same current flows through all of them.

• A circuit that only allows current to flow in one direction, preventing reverse flow.

• A circuit that includes a battery and a switch, but does not connect any components.

What is the role of a switch in a circuit?

• A switch is a device that can open or close a circuit, controlling the flow of electricity.

• A switch is used to increase the voltage in a circuit.

• A switch is a device that stores electrical energy for later use.

• A switch is used to measure the current flowing through a circuit.

What is a conductor?

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

• A material that prevents electricity from flowing, like rubber.

• A type of electrical device that stores energy.

• A material that only conducts heat, not electricity.

What is the positive terminal of a battery?

• The part of the battery where electric current flows out.

• The part of the battery that is connected to the ground.

• The part of the battery that stores energy.

• The part of the battery that is always negative.

What is a circuit?

• A circuit is a closed loop that allows electricity to flow from a power source, through components, and back to the source.

• A circuit is an open path that prevents electricity from flowing.

• A circuit is a type of electrical component that stores energy.

• A circuit is a device that converts electrical energy into mechanical energy.

What is a wire?

• A type of insulator that prevents electricity from flowing.

• A conductor that allows electricity to flow from one component to another in a circuit.

• A device that stores electrical energy for later use.

• A component that converts electrical energy into mechanical energy.
