  1. Electrostatics.The Methods of Charging.

  2. Electrostatics: • The Fundamental Rule: • Static Electricity: • Law of Conservation of Charge:

  3. Charging by Friction Positive • Rabbit’s Fur • Glass • Wool • Cat’s Fur • Silk • Felt • Human Skin • Cotton • Wood • Amber • Cork • Copper, Brass • Rubber • Sulfur • Celluloid • Cellophane Tape Charging by Friction: When two objects are rubbed together Electron affinityis the relative amount of love that a material has for electrons. The Triboelectric Series Negative

  4. Examples Charging by Friction • Grey strip (vinylite) • Negatively charged after rubbed with paper • Gains electrons • Clear strip (cellulose acetate) • Positively charged after rubbed with paper • Loses electrons

  5. Conductors and Insulators • Conductors are materials that permit electrons to flow freely from particle to particle. • Insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.

  6. Polarization Polarization: is the process of separating opposite charges within an object.

  7. Polarization • Hold the balloon next to a wall, and the wall becomes polarized. • This makes attraction possible.

  8. Induction • Induction: Induction charging is a method used to charge an object without actually touching the object to any other charged object.

  9. Conduction • Conduction: Charging by conduction involves the contact of a charged object to a neutral object. • It is often called charging by contact.
