PPT-Electric Charge and Static Electricity

Electric Charge All matter is made up of atoms Atoms contain Protons Neutrons 0 Electrons Law of Electric Charges The law of electric charges states that like charges repel and . Electric Charges. Electrons . can. . move. from one atom to another, but protons . cannot. move .. When an atom has . gained. electrons, it has more electrons than protons, and it is . negatively. WHAT IS STATIC ELECTRICITY?. . Static. . electricity. is . a. . FIELD FORCE . – . it. . can. . act. . over. . a. . distance. .. It. is . generated. by . FRICTION. .. The. . Van der . Graff.

Electricity Electric Current Currents are the rate that electricity flows thru a wire 2 types of currents: Alternating Current (AC) electricity flows back-n-forth like in a house Direct Current (DC) electricity flows in one direction like in a battery
