Is an eraser an insulator?
The insulating materials or elements have the valence electrons tightly bound. These electrons cannot be freed or loosened. They are poor conductors of electricity. A few examples of insulators are erasers, paper, glass, and cotton.Click to see full answer. Keeping this in view, what are 10 examples of conductors? 10 Electrical Conductors Silver. Gold. Copper….
The insulating materials or elements have the valence electrons tightly bound. These electrons cannot be freed or loosened. They are poor conductors of electricity. A few examples of insulators are erasers, paper, glass, and cotton.Click to see full answer. Keeping this in view, what are 10 examples of conductors? 10 Electrical Conductors Silver. Gold. Copper. Aluminum. Mercury. Steel. Iron. Seawater. Also, what are some good insulators? Insulators oppose electrical current and make poor conductors, due to lack of free electrons. Some common conductors are: Copper, Aluminum, Gold, and Silver (Water, and other metals). Some common insulators are: Glass, Air, Plastic, Rubber, Porcelain, and Wood. Don’t forget “Semi-Conductors”: Germanium and Silicon. Also to know, what materials can conduct electricity? Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood. Is water a conductor?What makes water a good conductor of electricity? Pure water is a poor conductor of electricity, but the water in oceans lakes and rivers always contains dissolved salts. Salts are formed with ionic bonds, and when dissolved in water, the ions are separated by the electric fields of the polar ends of water molecules.
