Conductor or Insulator 1

Front

What is the definition of a conductor?

Back

A conductor is a material that allows the flow of electric current or heat through it easily.

Front

What is the definition of an insulator?

Back

An insulator is a material that resists the flow of electric current or heat.

Front

Give an example of a common conductor.

Back

Copper is a common conductor used in electrical wiring.

Front

Give an example of a common insulator.

Back

Rubber is a common insulator used to coat electrical wires.

Front

What property of materials determines if they are conductors or insulators?

Back

The atomic structure and the presence of free electrons determine if a material is a conductor or an insulator.

Front

Why is rubber used for the handles of frying pans?

Back

Rubber is used because it provides heat insulation, preventing heat from transferring to the handle.

Front

What is the role of free electrons in conductors?

Back

Free electrons in conductors allow electric current to flow easily through the material.

Front

What is the role of free electrons in insulators?

Back

Insulators have very few free electrons, which prevents electric current from flowing.

Front

What is the difference between thermal conductivity and electrical conductivity?

Back

Thermal conductivity refers to a material's ability to conduct heat, while electrical conductivity refers to its ability to conduct electric current.

Front

What is an example of a material that is both a conductor and an insulator?

Back

Semiconductors, like silicon, can act as both conductors and insulators under different conditions.
