PHY 182, Spring, 2005

Week 9

 

  Main Objectives:
  • Be able to define capacitance and determine the capacitance of arrangements of conductors in simple cases.
  • Be able to explain why inserting a dielectric in a capacitor increases its capacitance.
  • Be able to calculate the equivalent capacitance for arrangements of several capacitors connected in series and parallel.
  • Be able to calculate the amount of energy stored in a capacitor.
  • Be able to simplify electric circuits using combinations of resistors in series and parallel
Tuesday Optional re-take of part of Exam II.
