What is a material that allows energy to pass through easily?

Back

Conductor: A material that allows electricity or heat to flow through easily.

Front

What happens when a circuit is open?

Back

The circuit is OFF, meaning electricity cannot flow.

Front

What happens when a circuit is closed?

Back

The circuit is ON, allowing electricity to flow.

Front

What is a circuit?

Back

A closed loop that allows electricity to flow from a power source to a device and back.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across common points.

Front

What is an example of an insulator?

Back

Rubber, glass, and plastic are common insulators.

Front

What is an example of a conductor?

Back

Copper and aluminum are common conductors.

Front

What is a switch in a circuit?

Back

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

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit.
