Ch 11 - Electric Charges

1. Electrostatics

   • Charge by Friction
     • Depends on how tightly material holds onto electrons
   • Charge by Induction
     • Requires grounding
   • Charge by Conduction
     • Contact from charged--> uncharged

2. Coulomb's Law

   • Fe=kq1q2/r2
   • Vector Quantity

3. Charge

   • Unit: Coulomb - [C]

4. Material Types

   • Conductor
   • Insulator
   • Semiconductor
   • Superconductor
