Are liquids and gases good insulators?
Gases are good insulators because most insulating materials which have gas filled pockets which means gases are good insulaters. Hope this helps :)
Why is fiberglass a good heat insulator?
materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
Plastic conductor or insulator?
plastic are insulators because metals are the only conductors.Any other materials which is not classified as metals are said to be insulator
Some examples of heat conductors and insulators?
Some examples of heat conductors are nickel, coalbolt, iron, steel Some examples of heat insulators are rubbber,glass,wood
A material that prevents electrons from flowing freely is called?
The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics, which can conduct Electricity.
What is the Difference between dielectric and insulator?
The difference between dielectric and insulator lies in its field of application.Dielectrics are used to store the electric charges, while insulators are used to block the flow of electric charges ( they more or less act like a wall).While all dielectrics are insulators (they don't allow the flow of electric charges through them) all insulators aren't dielectric because they can't store charges unlike dielectrics.
What are the conductors and insulators in a simple circuit?
All materials are conductors and insulators to some extent. Materials called "conductors" have very high conductivity, and materials called "insulators" have very low conductivity. Wires are the conductors in a circuit. Wires are usually wrapped with insulators so that accidental contact between wires does not cause a "short" and prevent the circuit from working as designed. Also, air is a good insulator that is usually implicitly present between the components of the circuit. These insulators are not drawn on a circuit diagram. They are represented by the absence of a connection drawn on the diagram. In a sense, they are not part of the "circuit", because they are not part the path taken by the vast majority of electrons. Resistors are a kind of electrical component that is between a conductor and an insulator. They can conduct electricity to some degree, but less than a wire. Capacitors contain an insulator called a "dielectric". This material does not allow electrons to pass. However, current can pass through a capacitor. Excess electrons can accumulate on one side of the capacitor, while electrons are drained from the other side. No electrons actually pass through the capacitor, but they seem to because the same number enter on one side as leave on the other.
Ceramic materials are often used for heat insulation because they have?
low heat conductivity.

What is electrostatic charges?
Charge can also be present on insulators and because these materials do not allow the charge to flow, this is called electrostatic charge

Why are insulators important in conserving energy?
because insulators are protection for energy
Why is the dielectric strength of vacuum infinite?
The dielectric strength of vacuum is infinite because there is no molecule in the vacuum.

The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics, which can conduct Electricity.
What is an example of an electrical insulator?
Rubber and wood are good electrical insulators because they don't let electricity pass through them.The best insulators in the world are uranium hexafluoride - used as the dielectric in UHV machines and also Barium Titanate [BaTiO(4)] Better to say that they resist the flow of charge - rather than 'don't let electricity flow through them'.
