There is an example of a bad thermal insulator.
They are used to stop electricity from flowing where it isn't needed or it can be dangerous.
Non-metals can be bad conductors.Good conductors are found in metals.Paper, wood, rubber, Teflon, and others are examples of poor conductors of electricity.Poor conductors of heat include air, lead, etc.
The human body is one of the examples of conductors.Plastic, Styrofoam, paper, rubber, glass and dry air are examples of insulators.
Conductors use free electrons to conduct electrical current.Poor conductors are made by impedanceators.Some conductors are copper, aluminum, gold, and silver.Glass, air, plastic, rubber, and wood are some of the common insulators.
Bad conductors.Good conductors allow electricity to pass through them.Bad conductors don't allow electricity to pass through them easily.There is an example of copper and aluminum.The example is Rubber, Wood.
