What is an example of a good conductor Milady?
Any material that easily conducts electricity. Examples of good conductors? Metal, copper, and water.
Which is considered a good conductor?
Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current. … Other materials that are sometimes used as conductors are silver, gold, and aluminum.
What are two types of electric current Milady?
Direct Current: *Constant, even-flowing, Travels in one direction, and produced by chemical means. Alternating Current: *Rapid and interrupted flow, Travels in two directions, and produced by mechanical means.
What is another name for materials that are non conductors?
Non-conductive materials, also known as insulators, are materials that either prevent or block the flow of electrons.
What is a good example of a good insulator?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
- Copper. One of the most commonly used metals to conduct electricity is copper. …
Is Diamond a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.
What type of current does electric files use?

|cataphoresis||process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole|
What are two types of electric current?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction.
