If asbestos is disturbed, its fibers can dislodge and become airborne. This makes the fibers easy for people to ingest or inhale. Insulation: Asbestos is resistant to fire, electricity, and water. It also is a natural soundproofing material. This makes it useful as an insulator for electrical...
That’s because metal is a great conductor of electricity. (In fact, so is the human body, which is why you can sometimes pass the shock on to an unsuspecting victim.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber...
Static electricity exists when there is a build-up of opposite charges on objects separated by an insulator. Static (as in "at rest") electricity exists until the two groups of opposite charges can find a path between each other to balance the system out. When the charges do find a mea...
When there aren’t any free electrons then electrical current cannot be conducted through the material. The outer electrons will dislodge only when the material is in an extremely strong electrical field. We refer to this action as breakdown and it usually causes physical damage to the insulator....
d) Static electricity is causes when objects of different materials come close to each other. 2. Which statement isnotcorrect a) in the triboelectric effect at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator) ...
What is thermal power plant? What is the job of the insulator in a circuit? a. To keep electric charges inside the pathway. b. To provide electricity. c. To transform electrical energy. d. To provide an unbroken path for electrons. ...
Dielectrics are designed to inhibit the passage of electricity. The functioning of the insulators is similar. The very recognized usage of dielectric material is seen in the condensers, where a semi medium isolates the conduction panels called an isolation material. Different condenser types are ...
