Static Electricity goals and review key

Goals

1. Describe what it means for an object to be charged or neutral.


2. Describe three methods of charging.


3. State coulombs law and use it to describe the size and direction of electrical forces.


4. Sketch the electric field lines around point charges, dipoles and plates.


5. Sketch equipotential lines around point charges, dipoles and plates.


6. Qualitatively describe electric field strength, electric potential energy and voltage/potential and distinguish between them.


7. Solve problems with Coulomb’s law and the equations for electric field strength, potential energy and voltage.


8. Qualitatively explain electrical phenomena like lightning, static cling, shocks, grounding.


9. Describe the charge of an electron and how it was determined.
   
   Review Key.
   Note That the answer to problem 9 is wrong and should be 111,803 N/C.
