What does a insulator and a conductor mean?
An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires, A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.
Can electricity pass through plastic?
For the flow of Electric Current, the material must contain free electrons. If there are no free electrons, then to conduct electricity the applied voltage must exceed breakdown voltage. Plastics under ordinary state does not have free electrons but if high voltage is applied then it can start conducting.
What are two examples of good insulators?
Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.
Why is copper a good insulator?
Answer 1Copper [CU] is NOT A GOOD INSULATOR. On the contrary, it is a very excellent conductor of both electricity AND heat! Answer 2Glass, some kinds of rubber, most plastics, vinyl. Most materials are SOMEWHAT conductive and act differently at different temperatures. PURE glass is one of the best insulators. Answer 3If copper was to be a bad conductor..then copper vessels and cables wodn exist,,it s a very good conuctorof heat and electricity
Materials that discourage the flow of electricity?
In electronics terms this is called a non-conductor or materials that have a high dialectric value. Also these materials may be called insulators. They may consist of plastic,glass,paper,mica,wax which are among the most common in electronics. The dialectric value is determined by how well electricity can or cannot pass through each of these materials.
Are insulators made of materials that electricity can flow through easily?
If you're talking about electrical insulators, then no, as an electrical insulator does not let electricity through.
Materials that do not conduct electrical charges at all are called insulators?
No material exists that doesn't conduct electrical charges at all. We call materials that conduct electrical charges poorly insulators; a material that didn't conduct electricity at all would be a perfect insulator.
What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
Does an insulator conduct electricity?
We use the term insulator, specifically electrical insulator, to refer to an object or material that does not conduct electricity to any significant degree.The term insulator, with no other explanation, is assumed to refer to electrical insulators. There are of course other materials which are used as insulation for heat. They provide thermal insulation and may or may not conduct electricity.
What does Good electrical insulator mean?
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
Are materials that electrical current cannot pass through?
Any material that electricity can't pass through is classed as an insulator. Examples of insulators are glass, ceramics, plastic, dry wood, and so on.
What is the difference between conduct and insulate?
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!
What a good insulators?
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.

A good electrical insulator?
Two good Insulators are foam and styrafoam
Why current cannot pass through a insulator?
Insulators are made of non conductive materials and that is the point. Insulators are used to prevent electrical current from leaving the circuit being utilized.
Why such materials are good insulators?
Dielectric meterials are good insulator materials
