  1. What is Electrical Field? Electric Field is the Area around a charge where the electrical forces are felt by another charge, q0.

  2. Let’s draw the forces: - q Attractive electrical force + q Repulsive electrical force

  3. Examples: Force around a positive charge Force around a negative charge

  4. What is Potential Difference? • Gravitational Potential Difference is A hA B hb

  5. Electrical Potential Energy • Charge moves from high potential A to low potential B A +++++++++++ A dA B db - - - - - - - - - - -

  6. Electrical Potential V V is the ratio Electrical Potential Energy of a qo with the qo

  7. Gravitational Potential Difference An object that has Gravitational Potential Energy can do work if ________________________

  8. Electric Potential Difference Electric Potential: Electrical Potential DIFFERENCE:

  9. Electric Potential Difference An electrical charge can do work if _________________________________ _________________________________

  10. Example: Work done by qo, (2x10-6C) is 5x10-5J. Find V.

  11. Unit for Ep J (joule) eV (electron Volt) 1eV is the change in potential energy of an e- when moved through a PD of 1 Volt. • 1eV=1.60x10-19J
