Brief Facts About Conductors:

Those materials that do not permit electrons to flow freely from particle to particle are bad conductors. i.e. Wood, Plastic, Rubber, Wool, and, Alcohol are some examples of bad conductors. All materials that permit electrons to flow freely from particle to particle are good conductors. An object made of a conducting material will permit a charge to be transferred across the entire surface of the object. i.e. Silver, Gold, Copper, Aluminum, Mercury, Steel, Iron, and SeaWater are examples of good conductors.
