hmm yes because they can also conduct electricity.
Yes metal can be held by contact
yes
In general, porcelain is not a conductor. It is considered an insulator. It is possible to make ceramics that will conduct, but the porcelain we normally find is a good insulator.
Teflon is an electrical insulator (not a conductor).
The electrical charge of aluminum is +3.
A proton has a positive electrical charge and an electron has a negative electrical charge.
Yes, a plasma is a gas with an electrical charge.
Rubber is one. :)
"Insulator" means that electrical charge can NOT flow through it easily.
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.
An electrical charge could be added to an insulator from another source of charge such as a voltage supply, or maybe from a Van de Graaff belt generator. {The one I used generated 50MV at about 12x10^-6 Amperes. }
Yes, a glass microscope slide is an electrical insulator. Glass is generally considered an electrical insulator.
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
It stops the flow of the electrical current.
I'm not sure if you could classify it as a conductor or and insulator. What happens is the laser imparts an electrical charge to the paper where it strikes it. Then the tone which is opposite charged adheres to the locations.
conductor-copper insulator-rubber
Plastic is an electrical and thermal insulator.
An electrical insulator.
Paper has of non -conductive or insulator classification when used in electrical terms.
