Insulators vs Conductors

Front

What is the definition of a conductor?

Back

A conductor is a material that allows electrons to move easily through it, facilitating the flow of electric current.

Front

What is the definition of an insulator?

Back

An insulator is a material in which electrons are not able to move easily, preventing the flow of electric current.

Front

Why is silver considered a good conductor?

Back

Silver has a high density of free electrons, allowing it to conduct electricity very efficiently.

Front

What is the role of insulators in electrical systems?

Back

Insulators prevent the unintended flow of electricity, protecting users and ensuring the safety of electrical systems.

Front

What happens to the flow of electricity in an insulator?

Back

In an insulator, the flow of electricity is restricted because the electrons cannot move freely.

Front

What materials are typically used as insulators in electrical applications?

Back

Common insulating materials include rubber, glass, plastic, and wood.

Front

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, the conductivity of conductors increases, while the conductivity of insulators decreases.
