Materials that are good conductors of electricity typically have free electrons that can move easily through the material in response to an electric field. Metals, for example, exhibit this property because of their atomic structure. Insulators, on the other hand, have tightly bound electrons that do not move easily, thus they are poor conductors of electricity. The conductivity of a material depends on the availability of free charges for carrying electric current.
Not all magnetic materials are good conductors of electricity. Some magnetic materials, like iron, nickel, and cobalt, are also good conductors of electricity, while others, like magnetite, are poor conductors. The conductivity of a material depends on factors such as its crystal structure and the mobility of its electrons.
Pencil lead is the poorest electrical conductor among the materials listed. While steel and glass are poor conductors, aluminum is a relatively good conductor of electricity.
No, cotton is an insulator and not a good conductor of electricity. Conductors are typically materials like metals that allow the flow of electric current, while insulators like cotton inhibit the flow of electric current.
With a thermal conductivity of 237 W/m.K aluminium is a good conductor of heat.
No, krypton is not a good thermal conductor. It is a noble gas and has very low thermal conductivity compared to other materials.

I am just wondering why nobody mentions about light as conductor of electricity?
No, cheese is not a conductor of electricity. Conductors are materials that allow electrical current to pass through them easily, while cheese is an insulator and does not conduct electricity.
Materials that are not good conductors of electricity include rubber, glass, and plastic. These materials typically have high electrical resistance and do not allow the flow of electric current easily.
Yes it is but it is not good for electricity!!

All of them. That's the definition of "conductor".

Conductors are materials that allow energy such as heat and electricity to pass through while insulators prevent the energy to flow. Most metals are considered good conductors while rubber is a good insulator.
Iron is the best conductor of heat among the materials listed. It has a high thermal conductivity, allowing heat to transfer quickly through it. Water and wood are poor conductors of heat, while air is a good insulator.
