Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A material that allows electricity to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily, such as rubber, wood, and plastic.

Front

What is a circuit?

Back

A closed loop that allows electrical current to flow from a power source, through a conductor, and back to the power source.

Front

What happens when a light switch is flipped on?

Back

The circuit is closed, allowing electricity to flow and power the light.

Front

What happens when a light switch is flipped off?

Back

The circuit is opened, stopping the flow of electricity and turning off the light.

Front

What is a complete circuit?

Back

A circuit that is closed and allows electricity to flow continuously.

Front

What is an open circuit?

Back

A circuit that is incomplete, preventing electricity from flowing.

Front

Can water conduct electricity?

Back

Yes, water can conduct electricity, especially when it contains impurities.

Front

What is an example of a good insulator?

Back

Rubber is a good insulator because it does not allow electricity to flow through it.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity by opening or closing the circuit.
