Sample Exam 2

Explore the conductivity and electric potential of two point charges or sheets of charges. Determine the maximum at the surface and observe how the electric field drops with distance. Compare the effects of different factors and generate values for both inside and outside the charged region. Consider the analogies to gravity and think of water pockets when connecting charges. Study the connectivity of plates in series and parallel configurations.

  1. Sample Exam 2 Exam 2 Review JH

  2. Try: +/- or -/+ or ++ or – two charges on point p!

  3. Try conducting pair!

  4. You can make similar problem using, two point charges or two sheets of charges

  5. Maximum happens at the surface (even for conducting sphere). In this non-cond. With uniform charge the E drops like r/R Other factors can be used. Both inside and outside values can be generated.

  6. Analogues to gravity, only vertical distance matter.

  7. Can you generated x for –ve x-axis side?

  8. If the sizes are different then you make the potential equal (KQ/R). If identical then make the charges equal Think off water pockets; when connected the water level is the same

  9. Serial: plates connected without intermediate junction Parallel: two junction each connecting two plates from the two capacitor
