Conductors, Insulators, and Circuits

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, plastic, and wood.

Front

What is a circuit?

Back

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

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow, making devices like light bulbs turn on.

Front

What is an open circuit?

Back

An open circuit is a broken loop that prevents electricity from flowing, causing devices like light bulbs to turn off.

Front

Which material is the best conductor of electricity?

Back

Copper is one of the best conductors of electricity.

Front

Which material is a good insulator?

Back

Styrofoam is a good insulator that helps keep things hot or cold.

Front

What happens when you remove the light bulb from a lamp?

Back

The circuit becomes open, and the lamp will not work.

Front

What is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat.

Front

What is electrical conductivity?

Back

Electrical conductivity is the ability of a material to conduct electricity.
