2 Electric Charges: Conductors and Isolators Electrical conductors are materials in which some of the electrons are free electrons These electrons can move relatively freely through the material Examples of good conductors include copper, aluminum and silver Electrical insulators are materials in which all of the electrons are bound to atoms These electrons can not move relatively freely through the material Examples of good insulators include glass, rubber and wood Semiconductors are somewhere between insulators and conductors

15 Electric Charges There are two kinds of electric charges - Called positive and negative Negative charges are the type possessed by electrons Positive charges are the type possessed by protons Charges of the same sign repel one another and charges with opposite signs attract one another Electric charge is always conserved in isolated system Neutral – equal number of positive and negative charges Positively charged
