Thermal Energy

Conductors vs. Insulaters

Thermal Definition

Thermal energy is a type of energy that has 3 types of heat, conductors,convection,radiation.

Thermal Facts

Thermal energy is a part of the total energy of any object.

Thermal energy is related to the temperature of an object.

The joule is the unit used to measure thermal energy.

Conductor's Electricity

  1. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.

Insulators Electricity

An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it very hard to conduct an electric current under the influence of an electric field. A perfect insulator does not exist, because a portion of the insulator could become electrically conductive if the voltage applied across it exceeds the breakdown voltage. This is known as breakdown voltage of an insulator. Some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to insulate electrical wiring and cables. Examples include rubber-likepolymers and most plastics. Such materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts).
