  1. Chapter 33 Electric Fields and Potential

  2. Chapter 33 • Electric field – a force field that fills the space around every electric charge or charges • Example: Electron Proton

  3. Chapter 33 • An electric field has both magnitude and direction • Therefore, an electric field can be represented using… VECTORS!!!

  4. Chapter 33 • Electric Field Strength equation: • E = F/q • Units for E are N/C or V/m

  5. Chapter 33 • Electric potential energy – energy a charge possesses due to its location in an electric field

  6. Chapter 33 • Electric potential – electric potential energy per charge • Electric potential = electric potential energy charge

  7. Chapter 33 • SI unit for electric PE is the JOULE. • SI unit for charge is the COULOMB. • SI unit for electric potential is the VOLT. joule • 1 volt = 1 coulomb

  8. Chapter 33 • Electric potential is commonly called VOLTAGE.

  9. Chapter 33 • Capacitor – a device used to store electrical energy • EX: a Van der Graff generator

  10. Chapter 33 Vocabulary • Capacitor • Electric field • Electric potential energy • Electric potential • Volt • voltage
