Goals
- Describe what it means for an object to be charged or neutral.
- Describe three methods of charging.
- State coulombs law and use it to describe the size and direction of electrical forces.
- Sketch the electric field lines around point charges, dipoles and plates.
- Sketch equipotential lines around point charges, dipoles and plates.
- Qualitatively describe electric field strength, electric potential energy and voltage/potential and distinguish between them.
- Solve problems with Coulomb’s law and the equations for electric field strength, potential energy and voltage.
- Qualitatively explain electrical phenomena like lightning, static cling, shocks, grounding.
- 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.
