a material is neither a good conductor nor a perfect insulator because the number of free electrons determine the conductivity of a material.when we charge the material by electrification the transfer of electrons from one body to another takes place.and the atom is ionized because in each atom electrons are attracted by other material and net charge on the body is positive.but this is not permanent nor temporary.as we know that earth is a charged body and charge on conductor can be discharge by earthing a conductor and it is no more conductor.similarly in insulators the aoms locally polarize by bringing close to any charged body and the charge on insulator is temporary because there is deficiency of electrons.if we continously charged the insulator material finally a stage is reached when it becomes conductor e.g when clouds are attracted they charged the air and air becomes conductor and lightening strikes,we also know that air is insulator but due to excess charging air becomes conductor.

Are train tracks conductors or insulators?
The rails are good conductors The wooden ties they rest on are insulators
What substances are the best insulators?
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.

Is plastic a condoctor?
The term plastic has a broad definition as regards materials. There are thousands of plastics. We often think of plastics as organic polymers, and we will generally find that these materials are not good conductors. Different substances added to plastics during production can change this, but we usually find that plastics do not support current flow, and, therefore, might best be considered insulators rather than conductors.
Are conductors good insulation materials?
No, insulators and non conductive.
Materials that are not good conductors or and not good insulators are called?
Semiconductors. They have conductivity between conductors and insulators and are used in electronic devices like transistors and diodes.
What is the name of materials that are not good conductors of electricity?

How do you know the difference between conductors and insulators?
Conductors allow the flow of electricity due to the presence of free electrons, while insulators inhibit electron flow. Conductors often have low resistance, while insulators have high resistance to the flow of electricity. Materials such as metals are good conductors, while materials such as rubber are good insulators.
Differences between conductors and insulators?
Conductors allow the flow of electric current due to the presence of free electrons, while insulators have tightly bound electrons that do not allow current to pass through easily. Conductors have low resistance to the flow of electricity, while insulators have high resistance. Materials like metals are good conductors, while materials like rubber and glass are good insulators.
Make a list of materials which are good conductors of heat and materials which are good insulators of heat from objects at home?
Generally, things that feel cold to touch (in a normal temperature room and no heating applied to them) are good conductors of heat (metals for example). Poor conductors tend to feel neither hot or cold under normal conditions (wood for example).
Are insulators good conductor of heat?
No, insulators are not good conductors of heat. Insulators are materials that do not easily allow heat to pass through them due to their high resistance to thermal conductivity. They are used to prevent the transfer of heat, maintaining a barrier between hot and cold environments.
How are conductor and insulators similar?
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.
Are train tracks conductors or insulators?
The rails are good conductors The wooden ties they rest on are insulators
What materials make the best conductors and insulators?
Conductors- Most types of metal. Copper and Aluminium are used these days. Silver is a very good conductor but it is expensive. Insulators- rubber, plastic and wood are good insulators in the solid state.
What makes good thermal insulators and conductors?
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
What carries electric current not easily?
Electrical insulators. Materials such as rubber, plastic, wood, air and some ceramics are all poor conductors of electricity, or good insulators.
