Good and bad conductor of electricity
Materials can be classified based on their electrical and thermal conductivity. Conductivity is a measure of how well a material allows the flow of electricity or heat. Here are the main classifications based on conductivity:
A) Electrical Conductors:
Definition: Materials that allow the easy flow of electrical charge (electricity).
Examples: Metals (copper, aluminum, silver), Graphite, Some solutions (electrolytes)
B) Electrical Insulators:
Definition: Materials that do not allow the flow of electrical charge.
Examples: Rubber, Glass, Wood, Plastic etc...
C) Semiconductors:
Definition: Materials with intermediate conductivity, between conductors and insulators.
Examples: Silicon, Germanium etc…
Good and bad conductor of heat
Materials can be classified based on their electrical and thermal conductivity. Conductivity is a measure of how well a material allows the flow of electricity or heat. Here are the main classifications based on conductivity:
A) Thermal Conductors:
Definition: Materials that allow the easy flow of heat.
Characteristics:
Efficient at conducting heat.
Heat is transferred through the material quickly.
Examples: Metals (copper, aluminum), Diamond, Silver
B) Thermal Insulators:
Definition: Materials that will not allow the flow of heat.
Characteristics:
Poor conductors of heat.
Reduce heat transfer.
Examples: Wood, Styrofoam, Fiberglass, Rubber
